✦ Synopsis

In a quest for ruthenium complexes having [RuNS 4 ] cores, a non-fluxional configuration, trans-thiolate donors, and exchangeable coligands L, [Ru(L)('pyS 4 ')] complexes have been synthesized 1). Alkylation of 1 with excess MeI yielded [Ru(PPh 3 )('pyS 4 '-Me 2 )]I 2 (2). [Ru(DMSO)('pyS 4 ')] (3) was obtained from [RuCl 2 (DMSO) 4 ] and 'pyS 4 ' 2-. The PPh 3 or DMSO coligands in 1, 2, and 3 proved to be very inert to substitution. Only the DMSO could be displaced by CO under drastic conditions yielding [Ru(CO)('pyS 4 ')] (4). Treatment of [RuCl 2 (CH 3 CN) 4 ] with 'pyS 4 ' 2-yielded [Ru('pyS 4 ')] 2
