New Homodinuclear Alkyl and Aryl Dithiophosphonato Cd(II) and Hg(II) complexes: Syntheses and Characterizations

Abstract

New Cd(II) and Hg(II) complexes of previously known five dithiophosphonic acids ((p-MeO-C6H4)PS(SH)(OR), HLn, (n= 1-5); R= 3-pentyl-, HL1; R=1-phenyl-1-propyl-, HL2; R= 4-tert-butyl benzyl-, HL3; R= diphenylmethyl-, HL4; R= 4-tert- butyl cyclohexyl-, HL5) were prepared and characterized. To do this, the dithiophosphonic acids involved were treated with stoichiometric amount of the corresponding metal salts in methyl alcohol. The complexes came of as powdery crystals and were recrystallized from chloroform. The pure complexes were characterized by using elemental analyses as well as mas-(ESI), FTIR-, Raman-, NMR- (1H, 13C, 31P) spectroscopies.
