Reactions of (Ph₃P)₃RuCl₂ with the  ammonium salt of alkylene dithiophosphoric acids in 1:1 and 1:2 stoichiometry gave complexes of the type (Ph₃P)₃Ru(Cl)[S₂POGO](A) and (Ph₃P)₃Ru[S₂POGO]₂(B), G= -CMe₂CMe₂-, -CH₂CMe₂CH₂-, -CH₂CEt₂CH₂- and -CMe₂CH₂CHMe-. Molecular weight determinations and IR and NMR (¹H and ³¹P) spectral data indicate a hexacoordinated octahedral structure. The dithioligand in (B) complexes show monodentate and bidentate chelating.
