A number of ruthenium (II) complexes containing an NNS chelating thioether ligand (L) have been synthesized and characterized by elemental analysis, UV-visible, IR and 1H NMR spectroscopy and cyclic voltammetry. Ru(L)(PPh3)Cl2 (1) has been characterized by X-ray diffraction. Structural features of (1) indicate a distorted octahedral coordination environment around the ruthenium(II) centre. The two chlorides are cis to each other with the Ru-Cl(1) bond trans to PPh3 longer than the Ru-Cl(2) bond. Several mixed-ligand complexes containing bipyridine, phenanthroline, 2-picolinate and oxalate were also isolated and the structure of one of the heterochelates has been solved. [Ru(L)(PPh3)(bpy)](ClO4)2 (2) has also been structurally characterized. The structure and properties of (2) correspond to the predictions based on the structure of (1).
