| 摘要: 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)(H2O)]}n (1)和{[Co(bix)(IPA)(H2O)]}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。 |

| Abstract: Using 1,4-bis(imidazol-1-ylmethyl)benzene (bix) and isophthalate (IPA) as co-ligands, two new Co/Ni coordination polymers, {[M(bix)(IPA)(H2O)]}n (2) (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). CCDC: 759693, 1; 759694, 2. |
