Abstract
Toluene-3,4-dithiolate complexes, [CH3C6H3S2As{S2P(OR)2}] and [CH3C6H3S2AsS2POGO] (R = o-, m-, p-C6H4Me; G = –CH2C(CH3)2CH2–, –CHCH3CH2(CH3)2C–), have been synthesized by reaction of toluene-3,4-dithiolatoarsenic(III) chloride [C6H3(CH3)S2AsCl] with ammonium salts of the corresponding O,O’-ditolyl/alkylene dithiophosphate by refluxing in benzene followed by stirring. These complexes have been characterized by elemental analysis and IR, 1H, and 31P NMR spectroscopy. Single-crystal X-ray diffraction analysis of [CH3C6H3S2As{S2P(OC6H4Me-m)2}] revealed distorted trigonal-bipyramidal geometry with an anisobidentate chelating mode of the ditolyl moiety in these complexes.
