Abstract

A series of seven coordination polymers based on Cd and potentially tetradentate pyridine based Schiff base ligand with different anions (CH3COO-, NO2-, Cl-, I-, N3-, SCN-), [Cd(L)(CH3COO)(OH2)]n (1),{[Cd2(L)2(NO2)2(CH3OH)2]·CH3OH}n (2), {[Cd2(L)2Cl2(CH3OH)2]·CH3OH}n (3), [Cd(HL)I2]n (4), [Cd3(L)2(N3)4]n (5), [Cd(L)(SCN)(OH2)]n (6) and [Cd(HL)(SCN)2]n (7) {HL = 2-pyridinecarbaldehyde isonicotinoyl hydrazone (HPCIH)} in order to rationalize the effect of the anion, have been synthesized and characterized by elemental analyses, FT-IR spectroscopy, single crystal X-ray data diffraction, etc. The results show the influence of the counter-ions on the coordination mode of the cadmium ion that is c..
