Cu(II) coordination polymers [Cu(tda)(phen)]1.5H 2 O ( 1a) , [Cu(tda)(py)] ( 2a ) and [Cu(tda)(bipy)(H 2 O)]0.5H 2 O ( 3a ) (tda = thiodibenzoic acid, phen = phenanthroline, py = pyridine, bipy = bipyridine) have been synthesized by slow diffusion. Under solvothermal conditions, [Cu(tda)(phen)]2H 2 O ( 1b) , [Cu(tda)(H 2 O)] ( 2b ) and [Cu(tda)(bipy)] ( 3b ) were isolated. The structures of the complexes 1a – 3a have been determined by single X-ray diffraction. The experimental X-ray powder diffraction patterns of 1b – 3b were compared with the calculated patterns of 1a – 3a . The polymers were found to exhibit structural and dimensional diversity due to the effect of the co-ligands. In complexes 1a and 1b , tda is found to coordinate with the metal atom in a monodentate mode, while in 2a and 2b , the carboxylate oxygens are coordinated with the two metal centers in a μ -bridged bidentate fashion. The structural analysis of 3a shows that the copper atom is in a square pyramidal environment, whereby the metal atom is coordinated with the carboxylate oxygens of two different tda ligands in a monodentate fashion and two nitrogens of the bipyridine ligand and one coordinated water. The IR spectrum of 3b implies a bidentate mode of coordination.
