186. Bis-Alkoxide Dysprosium(III) Crown Ether Complexes Exhibit Tunable Air Stability and Record Energy Barrier

Wen-Jie Xu, Qian-Cheng Luo, Zi-Han Li, Yuan-Qi Zhai, and Yan-Zhen Zheng*

Highlight: 高性能、空气稳定的单分子磁体(SMMs)可以为信息存储器件制备提供极大的便利。而镧系SMMs的高稳定性和强磁轴向性难以平衡,因此许多高性能镝(Dy)基SMMs对空气高度敏感,这限制了它们的实际应用。具有赝D6h对称性的Dy基配合物能够很好地结合大配位数和高对称性,是制备高性能空气稳定单分子磁体的优选构型。在此,我们选择弱的18-冠-6作为平面配体,大位阻醇氧配体金刚烷醇作为轴向配体,成功合成化合物[Dy(18-C-6)(1-AdO)2][I3],其同时具有良好的空气稳定性和显著增强的磁轴向性,展现出高达2427 K的创纪录能垒值和11 K的阻塞温度,为空气稳定型SMMs设立了新的基准。

185. Gd-based Molecular Coolants: Aggregating for Better Magnetocaloric Effect

Yuan-Qi Zhai, Wei-Peng Chen,* Marco Evangelisti, Zhendong Fu and Yan-Zhen Zheng*

Highlight: 作者通过溶剂热法成功合成了15种3d-Gd混金属磷酸酯配合物,其中包括7种仅含两个钆(III)离子的配合物({Gd2}、{Ni2Gd2}、{Co4Gd2}、{Co8Gd2}、{Fe6Gd2}、{Fe17Gd2})和8种含有超过两个钆(III)离子的复杂结构({Co8Gd4}、{Mn8Gd4}、{Co4Gd6}、{Mn4Gd6}、{Co6Gd8}、{Ni5Gd8}、{Ni6Gd6}、{Co8Gd8}、{Mn9Gd9})。在第一系列中,由于钆(III)二聚体周围环境的相似性,为研究磁交换作用对磁热效应(MCE)的影响提供了独特的视角。第二系列中,通过增加钆(III)中心的数量(加倍、三倍甚至四倍),作者进一步探索了在复杂环境下磁交换作用对MCE的影响。大多数配合物表现出反铁磁耦合,且MCE结果基本相似,但拓扑自旋阻挫的引入显著增强了MCE。尽管在磷酸酯配合物中观察到铁磁耦合的情况较为罕见,但本体系仍发现了一例具有出色MCE性能的配合物{Ni5Gd8},比热测试发现在1 T的低场磁熵变值达到10.7 J kg-1 K-1。此外,除了结构和拓扑的影响,作者发现磁熵变值(量度单位为焦耳/千克)与配合物中钆(III)离子所占的百分比线性相关,这为进一步理解和优化MCE提供了重要线索。

Highlight: 作者通过增大脒基配体取代基位阻合成出脒基稀土碘化物前驱体[Ln(Piso)2I] (Ln = Tb, Dy; Piso = {(NDipp)2CtBu}, Dipp = C6H3iPr2-2,6),并分别在强还原剂石墨钾以及强亲电试剂作用下分别合成并分离出首例非常规二价稀土脒基配合物[Ln(Piso)2]及其三价同构体[Ln(Piso)2][B(C6F5)]。研究发现,大位阻脒基配体可以很好地稳定二价稀土离子,使其呈现室温稳定的中性且线性的配合物结构。通过深入研究其磁性并结合紫外可见光谱、电子顺磁共振以及理论计算等手段,确定了二价镝和二价铽离子在该配体场下表现出4fn5dz21(Ln = Tb,n = 8;Dy,n = 9)电子构型。磁性研究表明二价铽与二价镝金属中心在此配体场下产生了非常大的磁各向异性,有效磁翻转能垒分别高达1920 K和1964 K,是目前二价单核单分子磁体的新纪录。

Qian-Cheng Luo and Yan-Zhen Zheng*

Highlight: 以往关于如何延长单分子磁体弛豫时间的研究主要集中在减轻磁量子隧穿效应上,但最近的研究进展表明拉曼弛豫更为关键。然而对分子体系中该弛豫机制的研究却属于是“贫瘠地带”,需要进一步被探索。本Forum文章系统梳理了单分子磁体磁弛豫过程的机制及对拉曼弛豫在分子体系的全新理解,强调了光学声子在该过程的关键作用,并通过最近几年的研究进展指出加强体系刚性和引入高能化学键对抑制拉曼过程的重要性,提出在将来结合磁光光谱技术和自旋动力学模拟等在该领域研究的必要性。总之,分子体系拉曼过程的研究是一个新兴领域,不仅对磁弛豫,而且对更广泛的物理科学具有更深的意义。

亮点:利用一种具有大空间位阻的“硬”碱配体,成功地制备了两例铒基配合物[ErCl(OArAd)3][Na(THF)6](1)和Er(OArAd)32)。在不同的溶剂环境中,由于配位氯的去除,Er(III)离子周围的配位几何结构从扭曲的四面体变为扁平的三角金字塔形。这种转变显著增强了单分子磁体(SMM)的行为,使后者场致有效势垒(Ueff)达到43(1) cm−1。结合理论计算表明,强平面配体场和高局部对称性对于抑制磁量子隧穿(QTM)和实现高性能铒基SMM至关重要。

Highlight: 报道了含有六氮杂三烯自由基(HAN·3-)和四种稀土(RE)离子的有机金属杂金属化合物[K(THF)6]{CoI[(μ3-HAN)RE2Cp*4]2} (1-RE) 和 [K(Crypt)]2{CoI[(μ3-HAN)RE2Cp*4]2} (2-RE)的合成和磁性能。1-RE显示出具有基于配体的混合价态的可分离物种,混合价态的强电子交换使2-RE中比含Gd和Dy离子的1-RE具有更强的整体铁磁行为。交流磁化率数据显示1-Dy和2-Dy都表现出缓慢的磁弛豫。重要的是,在2.0K下2-Dy的磁滞中观察到更大的矫顽力,表明与1-Dy相比,SMM行为增强。基于配体的混合价策略首次被用于改善镧系SMMs中的磁耦合,从而开辟了构建强耦合Ln SMMs的新途径。

亮点:环戊二烯(Cp)类配体构造出目前性质最优异的镝基单分子磁体,近期研究表明环丁二烯(Cb)类配体能够提供优于Cp类配体的晶体场劈裂效应,这是一个很好的契机挖掘具有潜力的配体来构建高性能的镝基单分子磁体。本工作使用赝烯丙基型氮,氮螯合脒类配体(Am)与五甲基环戊二烯基(Cp*)进行混配给出两例Dy(III)基单分子磁体(SMMs): [AmdippDyCp*(Cl)(μ-Cl)Li(THF)3]和[{(AmiPr)-DyCp*(μ-Cl)}2]分别具有472 K和97 K的有效能垒(Ueff)。通过与构型相似的单一环戊二烯类镝基单分子磁体的对比,发现前者Ueff值与基于单一Cp*配体的Dy(III)-SMM([Cp*2DyCl2K(THF)]n)相似,同时具有更长的QTM弛豫时间7.8 s;而后者的Ueff值则是明显高于同构型的单一Cp-SMMs([(η5-Cp)2Dy(μ-Cl)]2, [(η5-Cp)2Dy(THF)(μ-Cl)]2, [(PyCp2)Dy-(μ-Cl)]2)。通过晶体结构,磁性数据和理论计算的分析,本工作提出了一种具有潜力的脒类配体,总结出该配体具有一下优势:1)更加集中的电荷分布以提供强的轴向晶体场进而增强晶体场的分裂;2)螯合配位模式和金属-配体键有助于稳定分子。

亮点:在自旋电子和磁逻辑器件中使用自旋波的数据载体可在低功耗和无焦耳热的情况下运行,但需要小尺寸的非共线自旋结构。 由于在这种有限空间内的受控自旋波传输,异质金属环可以提供这种机会。 在这里,我们提出了一系列 {ScnGdn} (n = 4, 6, 8) 异金属环,它们是迄今为止第一个 Sc-Ln 簇,具有可调谐的自旋波激发磁相互作用。 通过时间和温度相关的自旋动力学模拟,我们能够预测 Sc4Gd4、Sc6Gd6 和 Sc8Gd8 在有限温度下的不同自旋波激发。 这种新模型以前未被开发,特别是由于反铁磁交换、偶极-偶极相互作用和低温下的环形拓扑的相互作用,体现出后者对自旋波激发的重要性。

亮点:单分子磁体(SMM)由于阻塞温度(TB)以下的长时间弛豫而被提出用于超高密度信息存储。然而,由于磁量子隧穿(QTM)效应,许多SMMs在零场区域遭受快速磁化损失。在这里,我们表明,大的基态磁矩的产生对于抑制SMM的零场QTM至关重要。我们使用氟桥连在一例3d-4f团簇中构建镧系离子之间产生铁磁耦合。该Dy3Cr3分子具有10.7 μB的大基态磁矩,并被确认为TB为5 K的SMM。更重要的是,在0.7 K的范围内观察到了矫顽场为1.3 T、剩磁超过97%的“非常硬”的磁滞回线。从头算计算完全支持此观察结果,从而说明氟桥对于抑制基于镧系元素的SMM的零场QTM的重要性。

亮点:如何抑制通过虚拟能级触发的快速拉曼弛豫过程已经成为化学上设计性能更好的单分子磁体的难题。在这里,我们使用三氟甲基系统地取代原有五角双锥构型Dy基单分子磁体轴向位置叔丁醇中的甲基。所得配合物-[Dy(OLA)2py5][BPh4](LA=CH(CF3)2)− 1,CH2CF32、CMe2CF33) -显示逐渐增强的TBhys(@100 Oe/s),从17 K(3)、20 K(2)到23 K(1)。通过实验确定了在5–500 cm-1范围内不同的低于第一激发态能垒的弛豫能,我们确定了轴向配体的C–F键在200到350 cm−1之间的相关振动能是这一改进的关键变量。总之,这一发现不仅揭示了几何结构与拉曼过程之间的相关性,而且为如何应用振动势垒模型分析镧系单分子磁体中的多声子弛豫过程提供了范例。

156.A C,S Bonded Quasi-Two-Coordinate Chromium(II) Complex Showing Field-induced Slow Magnetic Relaxation Behaviour

Qian-Cheng Luo, Ning Ge, Yuan-Qi Zhai, Teng-Bo Wang, Lin Sun,* Qi Sun, Fanni Li, Zhongwen Ouyang, Zhen-Xing Wang* and Yan-Zhen Zheng*

​​​亮点:尽管在过去几年中已经报道了大量由3d过渡金属离子组成的单分子磁体,但绝大多数是基于Co(II)、Fe(I、II或III),只有少数与Cr(II)离子有关,例如一些多核簇和四配位的单核配合物。此外,这些Cr(II)配合物中的配位原子主要是N和O原子。在此,我们成功地合成了一种C,S键合的单核Cr(II)化合物Cr(SAr*)21,HSAr*=HSC6H3-2,6(C6H2-2,4,6-Pri3)2),且在1500 Oe直流场下观察到了它的慢磁弛豫行为。利用MBO和AIM拓扑分析表明,Cr-S键可视为与格共价键,而Cr-C(ipso)相互作用更接近于离子键。通过直流磁测量、高频/场电子顺磁共振(HF-EPR)实验和从头算计算,可以确定1的相对较大的菱方特性。对模型配合物Cr(SPh)22)的进一步计算表明,消除分子内Cr-C(ipso)弱相互作用可以提高中心Cr(II)离子的磁轴向性。

亮点:成功地合成了一系列完全三明治结构的蛛网式碳硼烷镧系配合物,其结构为{η6-[μ-1,2-[o-C6H4(CH2)2]-1,2-C2B10H10]2Ln}{Li5(THF)10}(Ln=Tb,Dy,Ho,Er,Y),其中“碳邻接”的碳硼烷配体(arachno-C2B10H104-) 带有四个负电荷,并使用六边形η6-C2B4面与中心镧系元素离子配位。因此,中心镧系阳离子为伪十二配位,具有近似的伪D6h对称性或六角棱柱几何结构。由于这种几何结构带来的晶体场效应仍然未知,我们深入研究了这一系列配合物的磁性,发现该配体施加的晶体场导致基态和第一激发态之间的能隙为Tb>Dy>Ho>Er的关系,这与二茂铁和酞菁配体极为相似,尽管在两种配体下局部配位几何形状不同。此外,在优化磁场下,磁化反转效势垒达到445(10)K、最高可在4K观察磁滞回线,以及在2K下,钇稀释样品的弛豫时间达到193(17)秒,这一系列蛛网式碳硼烷镧系配合物的Tb类似物为Tb3+基单分子磁体提供了新的基准。

亮点:具有长时间保持磁矩的分子被认为是存储字节的最小单位,这可能给信息技术带来新的革命。然而,这种分子的合理设计仍然具有挑战性。本文成功地制备了具有五角双锥配位几何结构和局部D5h对称性的具有刚性金刚烷醇配体的镝(III)配合物:[Dy(1-AdO)2(py)5]BPh4-1和[Dy(2-AdO)2(py)5]BPh4-2,因为在低能状态下振动大大减弱,它们表现出良好的单分子磁体(SMM)行为(1Ueff≈ 1835K,TBZFC≈ 24K,TB100s≈ 17 K, TBH=23 K;2Ueff≈ 1756K,TBZFC≈ 20K,TB100s≈ 16 K和TBH=23 K)。值得注意的是,这些固态配合物的大势垒和高的阻塞温度在溶液中得到了很好的保持,这在先前的单分子磁体的研究中从未观察到,表明使用金刚烷醇作为轴向配体可以使得配合物阳离子结构具有很强的刚性,并且足够的稳定性使固态磁性维持在了溶液中。

亮点: 利用18-冠-6为中性平面辅助配体以及轴向的阴离子型配体,成功合成出一例局部具有六方双锥构型(C6v对称性)的镝基配合物[Dy(OtBu)Cl(18-C-6)][BPh4]。该化合物具有较高的磁化反转能垒(Ueff > 1000 K),但阻塞温度却非常低(TB < 4 K)。为了搞清楚其原因,与英国曼彻斯大学的Winpenny和Chilton合作,通过变温X射线单晶衍射研究(从273K冷却到30K), 并结合从头算计算,发现该化合物结构在低温下发生了Cl-Dy-OtBu角的弯曲,从而导致电子激发态能量降低了约10%。而在低温下,通过对磁弛豫速率的温度和场依赖性的深入研究表明,该化合物的磁弛豫过程受五种不同机制的共同影响,包括了Orbach、Raman-I型、Raman-II型、QTM和声子瓶颈效应等,因此磁阻塞效应受到了极大的削弱。

亮点:观察到溶剂效应对两种单分子磁体性能的影响。四氢呋喃和甲苯溶剂可以分别在[Dy(OtBu)2(4-PhPy)5]BPh4 1和Na{[Dy(OtBu)2(4-PhPy)4][BPh4]2hf·hex 2中将赤道配位的4-苯基吡啶(4-PhPy)分子从五个切换到四个。这种交替显著改变了D5h和D4h中Dy(III)中心的局部配位对称性。磁学研究表明,2的磁各向异性能垒高于1,而由于对称效应,阻塞温度的关系正好相反。静电势的计算成功地解释了溶剂对分子结构变化的驱动力,证实了通过不同溶剂调节SMMs性能的可行性。

Qian-Cheng Luo, Yan-Zhen Zheng*

亮点:理论计算在新兴的单分子磁体(SMMs)领域发挥着重要作用。 它不仅可以解释实验现象,还可以对合成进行指导。本综述重点讨论近年来在该领域中使用的计算方法。最常用和最有效的方法是完全活性空间自洽场方法(CASSCF),它可以很好地预测单核单分子磁体的性质。对于双核和多核单分子磁体,需要考虑磁交换,交换耦合常数可以通过蒙特卡罗模拟(MC)、通过POLY_ANISO程序的从头算计算和密度泛理论结合对称性破损态方法(DFT-BS)得到。此外还讨论了这些计算方法在设计高性能单分子磁体方面的进一步应用。

亮点:

单分子磁体是由磁性中心和有机配体组成的一系列配合物,而自旋和局域振动模式之间的耦合是磁弛豫的关键。由于自旋-声子耦合引起的振动势垒最近被证明为低于势垒弛豫和异常低的拉曼指数提供了解释,这两个难题已经困扰众多研究人员了几十年,并在许多实验中普遍存在。两项研究(Phys. Rev. Lett. 2020, 125, 117203  Phys. Rev. B 2021, 103, 014401)阐明了它们是多光学声子辅助拉曼过程的结果,介绍了这种弛豫机制的要点和广泛含义。该理论以量子方式统一理解了不同磁弛豫过程,也适用于更一般的体系。

亮点:具有高磁各向异性的镝化合物作为单分子磁体被广泛研究。本文用单晶方法研究了DyIIISMM {[Dy(OSiMe3)2(4-Mepy)5(BPh4)]0.5Toluene}中的各向异性磁热效应。由于高磁各向异性,在300 K时可以观察到角磁化。沿易轴方向测量的SMM行为与多晶样品相同。从易磁化轴到难磁化平面的旋转磁化19 KB= 5T时产生的最大磁熵变为3.05kJ/kgK,使DyIIISMM可用作低温旋转磁制冷剂。

Highlight:首例具有整数自旋值的二聚蜂窝状拓扑格子的二维范德瓦尔斯磁性材料被合成出来。该二维拓扑结构由铁及叠氮根组成,通过有机分子层间的范德华力叠加而成。该叠加最薄处只有十层,约13纳米厚。该材料兼具拓扑自旋阻挫及二维磁体的特性,表现出了新颖的再入型自旋玻璃和硬的磁体行为,矫顽场近2特斯拉。研究者坚信将二维磁体与拓扑自旋阻挫结合在一起能产生一些新奇的物理现象及材料特性,有可能开拓一个可供研究的新方向。后续工作将从减少材料的厚度、设计新的理想拓扑结构等着手开展,进一步揭示该类二维磁性材料的特性。相关结果在线发表在Advanced Functional Materials 上。

Highlights:本文通过在轴向上采用带有苯基的醇氧基配体,成功地引入分子内的C−H∙∙∙π作用和分子间的C−H∙∙∙π和π∙∙∙π相互作用,增强了分子的刚性,并有效地抑制了零场量子隧穿,合成出目前最硬的D5h单离子磁体。自旋动力学计算发现,轴向配体的化学修饰改变了奥巴赫弛豫过程的起始跃迁,进而改变了与跃迁共振的振动模式。由此可见,无论是磁偶极相互作用还是超精细耦合作用,都很可能不是导致零场量子隧穿的唯一原因。分子的转振动可能扮演着不可忽略的角色。

Highlight:镝基单离子磁体是目前最有发展潜力的磁性储存分子材料,但现有的高性能单离子磁体很难在空气中稳定存在。在保证强的磁各向异性的同时,端基氟离子的引入可以很好地解决稳定性问题。但由于氟和稀土具有非常强的亲和力,在合成过程中很难杜绝氟离子桥连或直接与稀土生成氟化物沉淀,因此端基氟配位的镝基单离子磁体极少被报道。这里我们报道了一例具有端基氟离子配位的镝基单离子磁体:[C(NH2)3]4[DyF(piv)4](piv)2,首次利用氢键网络保护的方式,稳定端基氟离子。通过磁性和超低温荧光的分析,我们发现此例化合物具有较高的能垒,其在高配位镝基单分子磁体中名列前茅。

Highlights:本文报道了一例基于磁交换耦合的单分子磁环{Fe8Dy8} 1Dy。磁性测试显示,{Fe8Dy8}分子内为铁磁交换作用,在0.5 K下的M-H曲线中,在0.23特斯拉处观察到明显的S型,这是环形磁矩的主要特征。运用从头算(ab initio)方法揭示了FeIII和Dy金属中心之间的铁磁交换相互作用是产生此环形磁矩的关键。为阐明该环状分子中的Fe-Dy磁性相互作用,进一步合成了两个类似的只具有一种顺磁金属中心的化合物{Fe8Y8} 1Y和{Al8Dy8} 2Dy。比较表明,Fe-Dy的铁磁交换相互作用导致1Dy的基态与第一激发态产生了明显的能级交叉。电子顺磁共振(EPR)测试得到能级劈裂场Hc为−3.35 T,基态和第一激发态之间的能隙为107 GHz (3.55 cm−1),和从头算得出的环形磁矩与微观态一致。该单分子磁环的基态为四重简并,这在以往报道的单分子磁环(SMT)中是前所未有的。由于磁交换耦合可以为配体设计提供更多选择,因此我们的工作为下一代单分子磁环的设计提供了有效策略。

Highlight:铅的毒性激发了人们对制备无铅光伏材料的兴趣,其中双金属双钙钛矿(DP)策略是制备铅碘钙钛矿替代物的一种有效方法。与目前流行的Ag(I)-Bi(III)基双钙钛矿不同,在之前的工作中我们发现Cu(I)-Bi(III)基双钙钛矿具有更窄的带隙,大约1.6 eV。在这个工作中我们将展示一种使用环状脂肪胺(CAAs)的合成策略,从中我们可以看到环脂肪胺对控制Cu(I)-Bi(III)碘化物DPs的结构尺寸、薄膜取向和带隙起到至关重要的作用。在这些化合物中,使用“Z形”六元环的CAAs可以得到二维的无机结构(化合物1-5),而使用具有“C形”五元环的CAAs时得到了一维无机链(化合物6和7)。无论结构尺寸如何,这7种化合物都显示出1.53-1.67ev之间的窄带隙。我们发现当Cu-I-Bi角接近180°或八面体畸变较小时,禁带宽度较窄。此外,DFT计算表明,这种带隙具有平坦和直接的性质。有趣的是,由这些化合物形成的薄膜由于胺的对称性不同而显示出了相对于ITO基底的优先取向。对于镜面对称的二胺,无机层倾向于垂直于ITO;对于不对称二胺,无机层倾向于在ITO上随机定向;对于不对称单胺,无机层倾向于平行于ITO。这种现象在钙钛矿薄膜的制备领域还没有被报导过。为了进一步揭示这些材料在光伏应用中的潜力,我们以化合物3为代表研究了它们的光电性能。从20℃到130℃,化合物3的电导率增加了5个数量级,从3.97×10-10s/cm增加到2.78×10-5s/cm,因此化合物3表现出了标准的半导体行为。同时光电流响应实验表明这种材料在光吸收方面具有潜在的应用。

Highlights:本文报道了使用银(I)和铋(III)代替铅(II)并获得两个基于二维(2D)碘化物的无铅双钙钛矿,即(AMP)4[BiAgI8]2.H2O 1和(APP)4 [ BiAg18] .H2O 2,其中AMP = 4-氨基甲基哌啶,APP = 4-氨基哌啶。与我们之前报道的基于1,4-环己二胺的化合物(C6H16N2)2 [BiAgI8] .H2O具有间接带隙相比,这两个新的2D Ag-Bi双钙钛矿由于其不易扭曲的[AgI6]单元而具有直接带隙〜2.00 eV。此外,光电流响应实验表明,两种化合物在light和dark之间的差异均超过50 nA,这表明其在光收集方面的潜在应用。1和2在热和湿气下也是稳定的。它们在95℃和90%RH下显示出高质子传导性(〜10-4 S cm-1)。因此,这项工作为设计具有直接带隙的稳定的无铅双金属碘化物双钙钛矿提供了一条新途径。

Highlights:本工作以JACS封面文章形式报导了一例罕见的六芒星状高核稀土-过渡金属纳米团簇——{Ni36Gd102}。该团簇具有良好的溶液稳定性,外围的金属镍离子在含氮、硫配位点的配体作用下可以选择性地在可见光催化将CO2还原为CO(90.2%),其TON为29700、转换频率为1.2 s−1,超过了多数同类型的催化剂。而该团簇含有的大量稀土钆元素则使该分子固体在2K 和ΔH = 7 T时,产生了41.3 J·kg–1·K–1的磁熵变,在低温磁制冷方面具有较好的应用潜力。该工作是我们整个稀土基纳米团簇研究课题的一个新起点,尤其是只含氮、硫配位原子的配体的引入及其无意中的原位硫酸根离子的生成对于该类材料的合成具有指导意义。而性质探索方面,此前未有报导利用团簇进行光催化还原二氧化碳分子的研究,该团簇催化下的二氧化碳还原不仅效率高、还具有很好的选择性,主要得益于具有可逆配位点的镍金属的存在,如何进一步利用该金属离子进行更有效的分子设计是留给我们的下一个课题。与此同时,如何利用团簇周围有机配体的S原子及团簇的单分散性将这类分子材料进一步器件化、并拓展其在表面磁制冷的应用也是我们需要深入思考的研究课题。目前,我们正对这些方向进行研究,希望将来能做出更多更好的工作。

Highlights:本文合成了三个具有相似BH4-Dy-BH4轴向配位环境的镝基硼氢化合物Dy(BH4)3(THF)3 (1), [Dy(BH4)2(THF)5][BPh4] (2) and [Dy(BH4)2(18-C-6)][Na(THF)2(18-C-6)][BPh4]2 (3),三个化合物均由两个三齿的BH4–配体占据轴向配位点,但是却有不同的平面配体场。其中,化合物1的平面配位数为4,分别有三个THF和一个二齿的BH4–配位,具有变形的八面体几何构型;化合物2的平面配位数为5,有5个THF配位,具有变形的D5h局部对称性;化合物3的平面配位数为6,由18-C-6的6个O原子进行配位,具有变形的D6h局部对称性。理论计算表明,这三个化合物的磁各向异性轴都接近于BH4-Dy-BH4轴。但是,由于不同的平面配位环境,化合物1仅在加场抑制量子隧穿效应以后才能表现出慢磁驰豫行为,能垒只有37(1) K;化合物2在零场下有不明显的单分子磁体行为;而化合物3在零场下更高温度表现出单分子磁体行为,能垒约为125(21) K。由此可以发现,弱化平面配体的配位能力,有利于提升单分子磁体的性能。
