Synthesis and characterization of ruthenium and osmium complexes of heterocyclic bidentate ligands (N, X), X = S, Se

The reaction of [RuCl2(PPh3)3] and [OsBr2(PPh3)3] precursors with a series of heterocyclic bidentate (N, X) ligands, X = S, Se, gave complexes [M(R-pyS) 2(PPh3)2], (R = H, 3-CF3, 5-CF 3, 3-Me3Si); [M(R-pymS)2(PPh3) 2], (R = 4-CF3, 4,6-MeCF3) and [M(R-pySe) 2(PPh3)2], (R = H, 3-CF3, 5-CF 3), where M is Ru or Os, pyS and pymS the anions of pyridine-2-thione and pyrimidine-2-thione, respectively, and pySe is the anion produced by the reductive cleavage of the Se-Se bond in the dipyridyl-2,2′-diselenide. All of the compounds obtained were characterized by microanalysis, IR, FAB, NMR spectroscopy and by cyclic voltammetry. Compounds [Ru(3-CF3-pyS) 2(PPh3)2] ? 2(CH2Cl 2) (2), [Ru(3-Me3Si-pyS)2(PPh3) 2] (4), [Ru(4-CF3-pymS)2(PPh3) 2] (5), [Ru(3-CF3-pySe)2(PPh3) 2] ? 2(CH2Cl2) (8), [Os(3-CF 3-pyS)2(PPh3)2] ? (CHCl 3) (11), [Os(3-Me3Si-pyS)2(PPh 3)2] (13), [Os(3-CF3-pySe)2(PPh 3)2] ? 2(CH2Cl2) (17), [Os(5-CF3-pySe)2(PPh3)2] ? 2(H2O) (18) and [OsCl2(4,6-MeCF3-pymS)(PPh 3)2] (19) were also characterized by X-ray diffraction. In all cases, the metal is in a distorted octahedral environment with the heterocyclic ligand acting as a bidentate (N, S) chelate system.

Metal-heterocyclic thione interactions-14. Synthesis and spectroscopic of ruthenium(II) complexes containing pyridine-2-thione and bis(tertiaryphosphines/phosphine sulphides)

A series of ruthenium(II) complexes containing pyridine-2-thione (C5H5NS) and bis(tertiary phosphine/ phosphine chalcogenide) are described. The complexes of stoichiometry, Ru(C5H4NS)2(L-L) (where L-L = Ph2P-CH=CH-PPh2 (dppen-PP) (1) Ph2P-CH2-P(S)Ph2 (dppm-PS) (2), Ph2P-CH2-CH2-P(S)Ph2 (dppe-PS) (3) and Ph2P(S)-CH2-CH2-P(S)Ph2 (dppe-SS (dppe-SS) (4)) are formed by the replacement of PPh3 from Ru(C5H4NS)2(PPh3)2 using a bis(tertiary phosphine) ligand in the presence of Et3N base in dry toluene under dry nitrogen. All these compounds have been characterised by analytical data, IR and NMR (1H and 13C) spectroscopy. Octahedral structures are suggested for the complexes in which diphosphines and pyridine-2-thiolate are chelating.
