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.
