| 摘要: 水热条件下，合成了两个新的配位聚合物[Cd(PhCOO)2(bmix)]n(1)和{[Cd(chdc)(bmix)]·C2H5OH}n (2)(bmix=1，4-双(2-甲基咪唑基-1-甲基)苯，H2chdc=1，4-环己二酸)。单晶结构分析表明，配合物1为一维锯齿状链结构平行于[001]平面；配合物2为层状结构，镉原子通过双配体桥连形成四连接的二维(4，4)网络。两个配合物中镉原子均具有6配位的畸变八面体几何构型，另外，测定了两个配合物的热稳定性。 |

| Abstract: The two Cd(Ⅱ) coordination polymers, [Cd(PhCOO)2(bmix)]n(1) and {[Cd(chdc)(bmix)]·C2H5OH}n (2) (bmix=1,4-bis(2-methylimidazole-1-ylmethyl)benzene, H2chdc=1,4-cyclohexanedicarboxylic acid) were hydrother-mally synthesized and characterized by elemental analysis, IR spectroscopy, TG and X-ray single crystal diffrac-tion. 1 possesses a one-dimensional zigzag chain structure parallel to [001]; 2 displays a two-dimensional undulated (4,4) network constructed with bmix and chdc dianion bridge ligands. Each cadmium(Ⅱ) ion in 1 and 2 has distorted octahedral coordination geometry. In addition, the thermal properties of two coordination polymers have been presented. CCDC: 842711, 1; 842712, 2. |
