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.
