SYNTHESIS AND CHARACTERIZATION OF DIALKYLDITHIOPHOSPHATE COMPLEXES OFINDIUM(III)

Treatment of indium(III) chloride with ammonium dialkyldithiophosphate in a 1: 3 molar ratio in benzene afforded [In{S2P(OR)(2)}(3)](R = Et, Pr-n, Pr-i). The chloro complexes [InCl3-n{S2P(OR)(2)}n] (n = 1, 2) c an be readily obtained by the reaction of indium trichloride with indi um tris(dialkyldithiophosphate) in benzene at room temperature. All th ese complexes were characterized by elemental analysis, IR, NMR (H-1, C-13 and P-31) [solution and solid state] and mass spectral data. In a ddition, the crystal structure of the complex [In{S2P(OPri)(2)}(3)] ha s been determined by single crystal X-ray diffraction.
