The complex [Pt(5,5'-dmbipy)Cl-4] (1) (5,5'-dmbipy is 5,5'-dimethyl-2,2'-bipyridine) was prepared from the reaction of H2PtCl6 center dot 6H(2)O with 5,5'-dimethyl-2,2'-bipyridine in methanol. The same method was employed to make [Pt(6-mbipy)Cl-4] (2) (6-mbipy is 6-methyl-2,2'-bipyridine). Both complexes were characterized by elemental analysis, IR, UV-Vis, H-1 NMR, C-13 NMR and Pt-195 NMR spectroscopy. Their solid state structures were determined by the X-ray diffraction method.
