Metal(II) complexes of the types [M(L)(m)Cl-2(H2O)(n)] and [Cu(L')SO4(H2O)(2)] [M=Co(II), Ni(II), Cu(II) and Cd(II), L=acetophenone salicyloylhydrazone (ASH) OHC6H4CONHN=C(CH3)C6H5, m = 2, n = 2; 4-hydroxyacetophenone salicyloylhydrazone (4-HOASH), m = 2, n = 0; acetophenone isonicotinoylhydrazone (AINH), NC5H4CONHN=C(CH3)C6H5, m = 1, n = 2; 4-hydroxyacetophenone isonicotinoyl-hydrazone (4-HOAINH), NC5H4CONHN=C(CH3)C6H4OH, m = 1, n = 2, and L'= 4-HOAINH and 4-HOASH] were prepared and characterized by elemental and thermal analyses, molar conductance, magnetic susceptibility, infrared, electronic, NMR, ESR and X-ray powder diffraction studies. Some of the complexes were screened against E. coli and Aspergillus niger to explore their biological activity.
