摘要

The coordination polymers {[Zn_2(HIDC)_2(tib)]·H_2O}_n (1) and {[Cd(HIDC)(tib)]·H_2O}_n (2) [H_3IDC = 1H-imidazole-4,5-dicarboxylic acid, tib = 1,3,5,-tris(1-imidazolyl) benzene] were obtained under hydrothermal conditions. Their structures were determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis and IR spectroscopy. Complex 1 exhibits a two-dimensional layer structure with a 6~3-hcb topology. Complex 2 has a three-dimensional structure with a pcu topology. It is shown that the carboxylate ligand can bear diverse structures regulated by metal ions. Additionally, the photoluminescence behaviors of complexes 1 and 2 are discussed.
