Synthesis and structural characterization of cobalt, nickel and copper phosphanylthiolato complexes

Neutral cobalt, nickel and copper complexes of a series of phosphanylthiol ligands PhnP(C6H4SH-2)3-n (n = 1, 2) have been synthesized and characterized by IR and NMR (1H and 31P) spectroscopy, FAB mass spectrometry and X-ray structural analysis. All of the compounds, with the exception of [Co(Ph2PC 6H4S-2}2], were synthesized by electrochemical oxidation of the anodic metal (cobalt, nickel or copper) in an acetonitrile solution of the appropriate ligand and a small amount of tetramethylammonlum Perchlorate as an electro- lytic carrier. The presence of an additional coligand (PPh3, dppe, dppm or bipy) in the cell led to the synthesis of mixed complexes in one step. The crystal structures of [Co[Ph2P(O)C 6H4S-2}2] (1), [Co2{PhP(C 6H4S-2)2}2(μ-N 2)(bipy)2] (2), [Ni2(PhP(C6H 4S-2)2}2] (3), [Ni2{PhP(C 6H4S-2)2}2(μ-dppe)]CH 2Cl2 (4), [Cu2[Ph2PC 6H4S-2}2(PPh3)2] (5), [Cu2(PhP(C6H4S-2)2}(PPh 3)2(CH3CN)] (6), [Cu2(Ph 2PC6H4S-2}2(μ-dppe)] (7) and [Cu2(Ph2PC6H4S-2} 2(μ-dppm)] (8) are discussed.

PPh(2-C6H4S)2 as a pincer ligand in nickel(II) and palladium(II) complexes - X-ray structure of [Ni{PPh(C6H4S)2}(PPh2Me)], [Pd2(μ-dppe){PPh (C6H4S)2}2] and [Ni{PPh(C6H4S)2}]2

The phosphanylthiol PPh(2-C6H4SH)2 reacts with the NiII and PdII complexes [MCl2L2] in the presence of NaOEt to give the mononuclear derivatives [M{PPh(C6H4S)2}L] [M = Ni, L = PPh3 (1), PPh2Me (2); M = Pd, L = PPh3 (3)]. The analogous reaction starting with complexes containing bidentate ligands [MX2(L-L)] produces different results depending on the ligand used. The complexes [M{PPh(C6H4S)2}(dppm)] [M = Ni (4), Pd (5)], with an unligated phosphorus atom in the diphosphane are obtained with bis(diphenylphosphanyl)methane (dppm), while the dinuclear complexes [M2(μ-dppe){PPh(C6H4S)2}] [M = Ni (6), Pd (7)] are isolated in the case of 1,2-bis(diphenylphosphanyl)-ethane (dppe). With 1,10-phenanthroline (phen), the complexes [M{PPh(C6H4S)2}(phen)] [M = Ni (8), Pd (9)] are obtained, but when 2,2′-bipyridine is used the dinuclear compounds [M{PPh(C6H4S)2}]2 [M = Ni (10), Pd (11)] are isolated instead. Complexes 10 and 11, which can be obtained starting from NiCl2 or [PdCl2(NCPh)2] respectively, afford complexes 1-7 when treated with the respective phosphanes in the appropriate stoichiometries. The structures of 2, 7 and 10 have been confirmed by X-ray analysis.
