      Synthesis and Spectral Characterization of Bismuth Dithiolate Derivatives of Disubstituted Diphenyldithiophosphates    
Atiya Syed*

The present work deals with the synthesis of four complexes with general formula [{(ArO)2PS2}Bi(SCH2CH2S)] (1-4), where Ar = 2,4-(CH3)2C6H3, 2,5-(CH3)2C6H3, 3,4-(CH3)2C6H3, and 3,5-(CH3)2C6H3, respectively. The reaction of [(ArO)2PS2Na], HSCH2CH2SH with Bi(NO3)3.5H2O in toluene in 1:1:1 molar stoichiometry afforded the complexes these complexes. These newly synthesized complexes have been characterized by elemental analysis, Fourier-transform infrared, and multinuclear nuclear magnetic resonance (NMR) (1H, 13C and 31P) NMR. The bismuth(III) atom is proposed to be surrounded by four sulfur atoms - two of dithiolate moiety and two from dithiophosphate moiety resulting in trigonal bipyramidal geometry with the fifth position being occupied by the lone pair of electrons.


Key words: Bismuth, Dithiophosphate, Dithiolate, Phosphorus.
