Synthesis and structural characterization of homo dinuclear phosphorus 1,1-dithiolate Cd(ii) complexes

In this thesis, 2,4-bis(3-methoxytolyl)-1,3-dithia-2,4 diphosphetane 2,4-disulfide which is formulated as [((CH3)C6H3(OCH3)-P(S)S)2] compound resynthesized. Two dithiophosphonic acids which were previously known were synthesized from the reaction of this compound with alcohols ([HS2P(R')(ORn)], HLn; R'=(CH3)C6H3(OCH3); R1= Ethyl-, L1; R2= 2-propyl-, L2). These acids were converted to corresponding ammonium salts, ([NH4][Ln]). The ammonium salts were further reacted with CdCl2.H2O to prepare dinuclear two new dithiophosphonato cadmium(II) complexes, ([Cd(µ-Ln)2(Ln)2]) in ethanol medium. The structures of the compounds were explained by elemental analysis, mass spectrometry (ESI), FT-IR, Raman, NMR (1H, 13C, 31P) spectroscopy.
