Abstract

Two novel 3D heterometallic coordination polymers, Ln(4)(mu(3)-OH)(2)Cu(6)I(5)(IN)(8)(OAc)(3) (Ln = Nd (1), Pr (2); HIN = isonicotinic acid, HOAc = acetic acid), have been synthesized under hydrothermal conditions and characterized by elemental, infrared, and thermogravimetric analyses and single-crystal X-ray diffraction. Both compounds are isostructural and crystallize in the monoclinic system, space group P2(1)/c. Both polymers are constructed from 2D lanthanide-cluster polymers based on the {Ln(16)} wheel-cluster and 1D copper-cluster polymers based on the {Cu(6)I(5)} cluster, which represent the first examples of 3D coordination frameworks created by using a combination of two different types of metal-cluster polymer units, namely, a high-nuclearity lanthanide-cluster polymer and a transition-metal-cluster polymer.

摘要

两种新型的三维异金属配位聚合物，Ln(4)(μ(3)-OH)(2)Cu(6)I(5)(IN)(8)(OAc)(3)（Ln = Nd (1)，Pr (2)；HIN = 异烟酸，HOAc = 乙酸），在水热条件下合成，并通过元素分析、红外光谱、热重分析和单晶X射线衍射进行表征。两种化合物同构，均结晶于单斜晶系，空间群为P2(1)/c。两种聚合物均由基于{Ln(16)}轮簇的二维镧系簇聚合物和基于{Cu(6)I(5)}簇的一维铜簇聚合物构建而成，这代表了通过结合两种不同类型的金属簇聚合物单元，即高核镧系簇聚合物和过渡金属簇聚合物，创建的三维配位框架的首个实例。
