Transition-metal complexes with sulfur ligands. 112. Synthesis and characterization of ruthenium complexes with [RuPS{sub 2}N{sub 2}] cores. Substitution, redox, and acid-base reactions of [Ru{sup II}(L)(PR{sub 3})(`S{sub 2}N{sub 2}H{sub 2}`)] (L = CO, PPr{sub 3} R = Pr or Cy) and five-coordinate [Ru{sup IV}(PCy{sub 3})(`S{sub 2}N{sub 2}`)]{dagger}

In order to find new ruthenium complexes with [RuPS{sub 2}N{sub 2}] frameworks, [Ru(PPr{sub 3}){sub 2}(`S{sub 2}N{sub 2}H{sub 2}`)] (2), (`S{sub 2}N{sub 2}H{sub 2}`{sup 2-} = 1,2-ethanediamine-N,N` -bis(2-benzenethiolate)(2-)), [Ru(CO)(PPr{sub 3})(`S{sub 2}N{sub 2}H{sub 2}`)] (7), [Ru(CO)(PCy{sub 3})(`S{sub 2}N{sub 2}H{sub 2}`)] (4), [Ru(PCy{sub 3})(`S{sub 2}N{sub 2}`)] (5), (`S{sub 2}N{sub 2}`{sup 4-} = 1,2-ethanediamide-N,N` -bis(2-benzenethiolate)(4-)), [Ru(Br)(PPh{sub 3})- (`Et{sub 2}S{sub 2}N{sub 2}H{sub 2}`)] Br (8), (`Et{sub 2}S{sub 2}N{sub 2}H{sub 2}` = 1,10-diethyl-2,3,8,9-dibenzo-1,10-dithia-4,7-diazadecane), and [Ru(Br)- (PPh{sub 3})(`(PhCH{sub 2}){sub 2}S{sub 2}N{sub 2}H{sub 2}`)]Br (9) (`(PhCH{sub 2}){sub 2}S{sub 2}N{sub 2}H{sub 2}` = 1,10-dibenzyl-2,3,8,9-dibenzo-1,10-dithia-4,7-diazadecane) were synthesized. The molecular structures of 2, 5 and 9 were elucidated by X-ray structure determination.
