Carbonyl complexes of ruthenium(II) with unsymmetrical phosphine-phosphinesulfide ligands of the type Ph2P(CH2)nP(S)Ph2, n = 1-4

Reaction of [Ru(CO)2Cl2]n, with ligands Ph2P(CH2)n P(S)Ph2 (n = 1(a), 2(b), 3(c), 4(d)) in 1:1 molar ratio produces complex cis[Ru(CO)2Cl2(P∩S)](1a) (P∩S = η2-(P, S) coordinated) and cis-[Ru(CO)2Cl2(P-S)](1b-d) (P-S = η1-(P) coordinated), while 1:2 molar ratio yields complex of the type cis-[Ru(CO)2Cl2(P-S)2](2a-d). The complex 2a undergoes partial decarbonylation reaction in CH2Cl2-hexane solution to give a new chelated complex [Ru(CO)Cl(P∩S)2] Cl(2a′). Abstraction of halide with AgClO4 from the non-chelated complexes 1b-d and 2a-d afford corresponding chelated complexes [Ru(CO)2Cl(P∩S)](ClO4)(3b-d) and [Ru(CO)2(P∩S)2](ClO4)2(4a-d). The molecular structure of the complex 2aκ has been determined by single crystal X-ray diffraction. The ruthenium atom is at the centre of slightly distorted octahedral structure having the two phosphorus atoms of the two chelated P, S coordinated ligands at trans to each other, one CO group and Cl atom completing the coordination sphere. Other complexes have been characterized by elemental analysis, IR, 1H and 31P {H} NMR spectroscopy.
