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

Abstract

New Cd(II) and Hg(II) complexes of five previously known dithiophosphonic acids ((pMeO-C6H4)PS(SH)(OR), HLn, (n= 1-5); R= 3-pentyl-, HL1; R=1-phenyl-1-propyl-, HL2; R= 4-tertbutylbenzyl-, HL3; R= diphenylmethyl-, HL4; R= 4-tert-butylcyclohexyl-, HL5) were prepared andcharacterized. To do this, the dithiophosphonic acids involved were treated with stoichiometricamount of the corresponding metal salts in methyl alcohol. The complexes came of as powderycrystals and were recrystallized from chloroform. The pure complexes were characterized by usingelemental analyses as well as mass-(ESI), FTIR-, Raman-, NMR- (1H, 13C, 31P) spectroscopies.
