摘要

溶剂热条件使4 ' -[对-（咪唑-1-基）苯基]-2,2 ':6 ',2 ' -三吡啶(L)作为桥接配体形成多核Co（II）化合物。一维配位聚合物[Co2(L)2(Cl)4]。5H2O， 1和离散的[Co2(L)(Cl)4(DMF)] 2,2，可以通过调节反应中CoCl2/L的比例选择性地得到。配合物2的一个特殊特征是出现了由氯原子桥接的四面体和八面体Co中心，而Co（II）在1中是六配位的。这两种化合物的晶体结构已通过单晶x射线衍射研究进行了表征。磁性研究已经证明了2的倾斜反铁磁（即弱铁磁）行为。

Discrete and 1D Co(II) Coordination Compounds with Bridging Imidazole-Functionalized Terpy

Solvothermal conditions enable the formation of polynuclear Co(II) compounds with 4′-[p-(Imidazol-1-yl)phenyl]-2,2′:6′,2′′-terpyridine (L) acting as a bridging ligand. 1D coordination polymer [Co₂(L)₂(Cl)₄].5H₂O, 1, and discrete [Co₂(L)(Cl)₄(DMF)]₂, 2, can be selectively obtained by tuning the CoCl₂/L ratio involved in the reaction. A peculiar feature in complex 2 is the occurrence of tetrahedral and octahedral Co centers bridged by a chloride atom, whereas Co(II) is six-coordinated in 1. The crystal structures of both compounds have been characterized by single-crystal X-ray diffraction studies. Magnetic studies have evidenced a canted antiferromagnetic (i.e., weak ferromagnet) behavior for 2.
