ABSTRACT
Metal(II) complexes of the types [M(L)mCl2(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 isonicotinoylhydrazone (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.
