The two Cd(II) coordination polymers, [Cd(PhCOO)(2)(bmix)](n) (1) and {[Cd(chdc)(bmix)]center dot C2H5OH}(n) (2) (bmix=1,4-bis (2-methylimidazole-1-ylmethyl)benzene, H(2)chdc=1,4-cyclohexanedicarboxylic acid) were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, TG and X-ray single crystal diffraction. 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.
