Mixed Ligand Complexes of Gold (III) with Some Amino Acids and Dithiocarbamates or Dithiophosphates
Complexes of the type [Au(L)(L-orL=)]Cl were prepared [L= deprotonated glycine (Gly), Alanine (Ala), Valine(Val) or Methionine (Met), L- = N-Methylcyclohexyldithiocarbamate(N-MeCHdtc) or Benzyldithiocarbamate(Bzdtc) anion and L= =0,0-Dipropyldithiophosphate (DiPrdtp) or 0,0- Dibenzyldithiophosphate (DiBzdtp) anion. The prepared complexes were characterized by elemental analysis, molar conductivity, IR and UV-Vis spetra, magnatic susceptibility and (1H-nmr) for some of the complexes. The gold(III) complexes were all square planar with the dithiocarbamates or dithiophosphates acted as bidentate ligands coordinated through the two sulfur atoms and the aminoacid anions coordinated through N and O except for the methionine ligand which coordinate through S and N atoms.
