The coordination capability of the phosphinothiol ligands Ph 2PC6H4SH-2 and PhP(C6H 4SH-2)2, towards two organotin (Ph3SnCl, Ph2SnCl2) and the organolead Ph2PbCl 2 was studied. The complexes were characterized by microanalysis, FAB mass spectrometry, IR and NMR spectroscopy. Also, crystal structures of [Ph3Sn{Ph2PC6H4S-2}], [Sn{PhP(C 6H4S-2)2}2] and [Pb{Ph 2P(O)C6H4S-2}2]·1/2CH 3OH·2H2O complexes have been determined. The structure of [Ph3Sn{Ph2PC6H4S-2}] complex shows the triphenyltin fragment coordinated to one monoanionic phosphinothiol ligand acting as monodentate through the thiolate sulfur atom with the tin ion in a tetrahedral environment. The crystal structure of [Sn{PhP(C6H4S-2}2] shows the metal ion in a distorted octahedral geometry. The geometry about the Pb in [Pb{Ph 2P(O)C6H4S-2}2]·1/2CH 3OH·2H2O complex is best described as distorted ψ-trigonal bipyramidal with the five position occupied by the active lone pair of metal. Intermolecular weak Pb-(η6-C6H 5) interactions between the lead electron pair and phenyl rings are also observed.
