Syntheses and molecular structures of ruthenium complexes with dithiophosphate ligands

Reactions of [Ru(PPh3)3Cl2] and [RuHCl(CO)(PPh3)3] with K[S2P(OEt)2] in THF afforded [Ru{S2P(OEt)2}2(PPh3)2] (1) and [RuH(CO){S2P(OEt)2}(PPh3)2] (2), respectively. The crystal structures of complexes 1 and 2 have been determined by X-ray crystallography. The ruthenium atom in both molecules of 1 and 2 adopt an octahedral configuration. The average Ru–P and Ru–S distances in 1 are 2.3324(10) and 2.4974(11) Å, respectively. The corresponding bond lengths for 2 are 2.3551(9) and 2.5474(11) Å.
