    Abstract:
    Coordination of 2,3-diphenyltetrazolium-5-thiolate (tet) to an Ru(trpy)(bpy)(OH2)2 (trpy=2,2′:6′,2″-terpyridine; bpy=2,2′-bipyridine) centre resulted in the formation of [Ru(trpy)(bpy) (tet)](ClO4)2. Single-crystal X-ray analysis revealed that the tet ligand is bound through the sulfur atom to a somewhat distorted-octahedral ruthenium centre. The Ru-S bond distance is 2.393(2) Å, and the Ru-S-C bond angle is 115.1(2)°; the tet N-N bonded distances [1.306(10) Å-1.316(9) Å] are essentially equal. These data, as well as spectroscopic and electrochemical evidence, suggest that the tetrazolium ring exhibits delocalized, mesoionic character with some thiolate character on the sulfur atom.
