PREPARATION AND CHARACTERIZATION OF MN-II, CO-II, NI-II, CU-II AND ZN-II KANAMYCIN COMPLEXES

Binuclear complexes of manganese(II), cobalt(II), nickel(II), copper(I I) and zinc(II) with kanamycin sulphate have been synthesized and char acterized by elemental analysis, IR, H-1 NMR, electronic and ESR spect ra in order to throw more light on their structures. The spectral resu lts obtained indicate octahedral geometry around manganese(II), cobalt (II) and nickel(II), distorted octahedral geometry around copper(II) a nd tetrahedral geometry around zinc (II) ions.
