  • Abstract

    Antimony complexes of the type [Sb{S2P(OR)2}nCl3-n] (where R = o-, m-, p-C6H4Me; n =1-2) have been obtained by the reaction of antimony(III) chloride with ammonium salts of O,O-di(o-, m-, p-tolyl) dithiophosphates in 1:2 and 1:1 molar ratio by stirring followed by refluxing in benzene. All these complexes have been characterized by elemental analysis and IR, 1H and 31P NMR spectroscopy. On the basis of experimental and spectroscopic studies distorted trigonal bipyramidal geometry (tbp) around antimony having a lone pair of electron, at axial position may be proposed for the complexes corresponded to [(o-, m- or p-MeC6H4O)2PS 2SbCl2] while an octahedral geometry with a lone pair of electrons may be suggested for the complexes [{(o-,m- or p-MeC6H4O)2PS 2}2SbCl].
