The synthesis of the heterotopic P,SAs ligand, 1-Ph2AsSC 6H4-2-PPh2 (1) and its reaction with [PdCl 2(cod)], [PtI2(cod)] (cod = 1,5-cyclooctadiene) and NiCl2·6H2O is reported. Cleavage of the As-S bond of 1 and coordination of the resulting phosphanylthiolato ligand (SC 6H4-2-PPh2)- (SC6H 4-2-PPh2 = P,S) was observed with formation of [M(P,S)2] (M = Ni, Pd, Pt). In the case of Pd and Pt, not only the mononuclear complexes [M(P,S)2] formed, but also the trimers of [MX(P,S)] ([MX{(μ-S-SC6H4-2-PPh2)- κ2S,P}]3 [M = Pd, X = Cl (2) and M = Pt, X = I (4)]). Formation of 2 and 4 was preceded by the trinuclear isomeric intermediates [(cis-M{(μ-S-SC6H4-2-PPh 2)-κ2S,P}2)-MX2-MX{(μ-S- SC6H4-2-PPh2)-κ2S,P}] [M = Pd, X = Cl (3) and M = Pt, X = I (5)]. The crystal structures of 1-5 and a possible reaction mechanism that leads to 2 and 4 are presented.
