| Abstract: | Reactions of palladium(II)/platinum(II) chlorides with sodium salts of pyridine-2-thione (Na+C5H4NS-) or l-hydroxypyridine-2- thione(Na+C5H4NOS-) yield products of composition, Pd(C5H4NS)2 (1), Pd(C5H4NOS)2 (2) and Pt(C5H4NOS)2 (3). Reactions of 1-3 with triphenyl- phosphine gave Pd(C5H4NS)2 (PPh3)2 (4), Pd(C5H4NOS)2 (PPh3) (5) and Pt(C5H4NOS)2 (PPh3)2 (6). All the complexes have been characterised by analytical data, IR, far IR and multinuclear (1H, 13C, 31P) NMR spectroscopy. It is observed that whereas 1 and 2 show one type of isomer, 3 exhibits cis-trans isomerism in the ratio of 1:2. |
