Abstract

A series of first row transition metal binuclear complexes[(M)2(L1- 3)2(H2O4)][M=Co(II), Ni(II), Cu(II) or Zn(II)] with Schiff base ligand have been synthesized and characterized by elemental analysis, spectral studies, molar mass and molar conductance as well as magnetic moment and magnetic susceptibility measurement methods. On the basis of above physicochemical and spectrometric measurements it is proposed that the compounds act in a bi-dentate manner. Such complexes have varieties of useful pharmaceutical activities and many of them gained wide acceptance in clinical practices. The Schiff base and its resulting complexes have been tested for their antifungal activity against various organisms. Excepting Zn(II) all complexes are colored. Molar conductivity range supports non-electrolytic nature of the complexes. Electronic spectral bands and magnetic susceptibility study suggest an octahedral stereochemistry for the complexes.
