title: Ruthenium(II) thiol and H2S complexes: synthesis, characterization, and thermodynamic properties.
abstract: The known, green, five-coordinate species trans-RuCl(2)(P-N)(PPh(3)) react with R'SH thiols to give yellow cis-RuCl(2)(P-N)(PPh(3))(R'SH) products (P-N = o-diphenylphosphino-N,N'-dimethylaniline; R' = alkyl). The MeSH and EtSH compounds are structurally characterized, with the former being the first reported for a transition metal-MeSH complex, while the thiol complexes with R' = (n)Pr, (i)Pr, (n)Pn (pentyl), (n)Hx (hexyl), and Bn (benzyl) are synthesized in situ. Other trans-RuX(2)(P-N)(PR(3)) complexes (X = Br, I; R = Ph, p-tolyl) are synthesized, and their H(2)S adducts, of a type reported earlier by our group, are also prepared. Thermodynamic data are presented for the reversible formation of the MeSH and EtSH complexes and the H(2)S analogues. The Ru(II)Cl(2)(P-N)(PPh(3)) complex in solution decomposes under O(2) to form [Ru(III)Cl(P-N)](2)(μ-O)(μ-Cl)(2).
