Abstract: Three coordination polymers of cadmium and zinc {[Cd2(CPhIDC)(bimb)]·H2O}n (1), {[Cd2(CPhIDC)(phen)2]·3H2O}n (2), {[Zn2(CPhIDC)(bpp)]·1.5H2O}n (3), (H4CPhIDC=2-(4'-carboxyphenyl)-1H-imidazole-4,5-dicar-boxylic acid, bimb=1,4-bis(imidazol-1-yl)butane, phen=1,10-phenanthroline, bpp=1,3-di(pyridin-4-yl)propane) have been synthesized by solvothermal reaction and characterized by IR, EA and PXRD. Single crystal X-ray diffraction shows that the H4CPhIDC ligand presents fully deprotonated motifs of CPhIDC4- in three corresponding polymers. Moreover, the fully deprotonated ligands coordinate in the μ4 and μ5 manner to generate 2D and 3D polymers, displaying three different coordination modes. Complexes 1 and 3 exhibit 3D structures with (3,4,5)-connected frameworks with (5·6·7)(4·52·6·72)(4·52·6·74·82) topology, but the metal ions and auxiliary ligands are different. 2 displays a 2D wave-like fishing nets structure with 44·62 topology. The fluorescence spectra in the solid state and DNA binding properties of the polymers and ligand are investigated.
