| 摘要: 水热条件下,以1,4-双(咪唑基-1-甲基)苯(bix)及方酸阴离子(C4O42-)为配体,合成了新的镉的配位聚合物[Cd(C4O4)(bix)(H2O)2]n(1)。单晶结构分析表明，该配合物为二维层状结构，镉中心为六配位八面体结构，赤道平面上4个配位原子分别来自方酸和bix配体，轴向2个配位原子来自配位水分子，镉原子通过双配体桥连形成四连接的二维(4，4)网络。同时，测定了配合物的热稳定性和荧光性质。 |

| Abstract: A coordination polymer [Cd(C4O4)(bix)(H2O)2]n(1) has been synthesized by using 1,4-bis(imidazole-1-ylmethyl)benzene (bix) and squarate dianions (C4O42-) as ligands. The single crystal structural analysis showes that 1 is a 2D sheet-like network. The cadmium centers are six coordinated with two O atoms from two C4O42-, two N atoms of two bix ligands and two O atoms of two coordination water molecules. The structure can be described as a 4-connected 2D (4, 4) network. In addition, the thermal and luminescent properties of the coordination polymer have been studied. CCDC: 838750. |
