Synthesis, Characterization , Evolution. Of Antibacterial Activity Of Co (II) , Ni(II), And Pd (II) Complexes With Bis Dithiocarbamate And Phosphine Ligands.
Abstract
Reaction of metal salts CoCl2.6H2O,NiCl2.6H2O and Na2]PdCl4[ with thymine bis- dithiocarbamate and uracil bisthiocarbanmate in molar ratio 2:1(Metal Ligand) afforded the Presumably tetrahedral Complexes ]M2(dtc)(H2O)4Cl2] M; Co,Ni and square Planer Complexes [Pd (dtc) (H2O)4 Cl2] dtc = tdtc, utdc. Dithiocarbamates behaves as monodentate ligands . Reaction of [ M2 dtc (H2O)4Cl2]. M ; Co (II), Ni (II) and Pd(II) with Ph2P CH2 CH2 PPh2 " (two equivalent) and PPh3 ( four equivalent) afforded tetrahedral Complexes of type [M2 dte( Phosphine)n Cl2] M;Co, Ni and square planer Complexes [Pd2 dte(phosphine)n Cl2] n=2 or 4, bis(dithiocarbametes) acts as a monodentate Ligand and binded to the metal center through the soft sulfur atoms .The Complexes were characterized by Physico Chemical and spectroscopic methods
