两个二维层状4-双(咪唑基-1-甲基)-苯钴和镍配位聚合物的合成与表征

Synthesis and Characterization of Two 2D Layered New Coordination Polymers of Co/Ni with the Ligand of 1,4-Bis(imidazol-l-ylmethyl)benzene

以1,4-双(咪唑基-1-甲基)-苯(bix)为配体,间苯二甲酸(IPA)为辅助配体,合成制备了两种新型同构配位聚合物:{[Ni(bix)(IPA)(H_2O)]}_n(1)和{[Co(bix)(IPA)(H_2O)]}_n(2)。单晶结构表明,此两个配合物均形成二维层状空间结构,金属原子均为六配位八面体结构,赤道平面上四个配位原子来自间苯二甲酸和配位水分子,轴向两个配位原子为bix配体的咪唑环上的N原子。金属原子通过配体连接形成四连接的二维4(4).6(2)方格层状结构。

Using 1,4-bis（imidazol-1-ylmethyl）benzene（bix） and isophthalate（IPA） as co-ligands,two new Co/Ni coordination polymers,{[M（bix）（IPA）（H_2O）]}_n（M=Ni,1;Co,2） have been synthesized.Single crystal structural analyses reveal that 1 and 2 are isostructural and possess a 2D square sheet-like network.The metal ions are six-coordinated with three O atoms from two IPA ligands,one O atom of coordinated water and two N atoms of two bix ligands,respectively.The network can be described as an uninodal 4-connected 2D net with a point symbol of 4（4）.6（2）.
