摘要：

Two new Cd(II) coordination polymers, [Cd(C4H6N2)(2)(C4H2O4)(H2O2)](n) (1) (where C4H6N2 = 2-methylimidazole, C4H2O4 = fumarate), and [Cd(C4H6N2)(H2O)(C4H4O4)](n)center dot nH(2)O (2), (where C4H4O4 = succinates), have been prepared and structurally characterized by single crystal X-ray diffraction. Complex I crystallizes in the triclinic space group P (1) over bar in a one-dirnensional chain structure, in which carboxy is monodentate; a three-dimensional supermolecular network structure was formed through hydrogen bonding. In complex 2, the coordination geometry of the Cd atoms is it pentagonal bipyramid, and a two-dimensional sheet is formed though carboxyl group bridging. In 1 and 2, IR spectra indicate the presence of bridging carboxyl groups, confirmed by structure analyses.
