New Cd(II) complexes, Cd(II)(TC-1), Cd(II)(TC-2)₂ and [Cd(II)(TC-3)₂•2CH₂Cl₂]₂ (TC-1 = methyl(2-(pyridine-2-yl)ethyl)dithiocarbamate, TC-2 = ethyl(pyridine-2-yl)methyl)dithiocar-bamate, TC-3 = bis(pyridine-2-ylmethyl)dithiocarbamate, have been synthesized and characterized by means of IR, NMR, TGA/DSC, and X-ray crystallography. Interestingly, these Cd(II) complexes have different coordination geometry despite the similarity of the ligands structure. Cd(II)(TC-1)₂ shows a 1-dimensional linear coordination polymer structure and Cd(II)(TC-2)₂ shows a 2-dimensional coordination polymer structure. [Cd(II)(TC-3)₂•2CH₂Cl₂]₂, however, show discrete cyclic dimer structure. In crystal structure of Cd(II)(TC-2)₂, central Cd(II) atom is 6-coordinated with two nitrogen atoms of pyridine ring and four sulphur atoms of two dithiocarbamate ligands, in which two dithiocarbamate ligands bonded in a bidentate fashion. In Cd(II)(TC-1)₂ and [Cd(II)(TC-3)₂•2CH₂Cl₂]₂, the cadmium atom adopts square pyramidal arrangement, that is, Cd(II) is coordinated by four sulphur atoms of two dithiocarbamate ligands and one nitrogen atom from pyridine ring.
