STUDIES ON COMPLEXES OF Co(II), Ni(II), Cu(II), AND Cd(II) WITH ACETOPHENONE AND 4-HYDROXYACETOPHENONE BENZOYLHYDRAZONES

摘要

Metal(II) complexes of the types (M(L)_2Cl_2) centre dot H_2O and (Cu(4-HOABH)SO_4(H_2O)_2) (M = Co(II), Ni(II), Cu(II) and Cd(II), L = acetophenone benzoylhydrazone (ABH), C_6H_5CONHN = C(CH_3)C_6H_5 and 4-hydroxyacetophenone benzoylhydrazone (4-HOABH), C_6H_5CONHN = C(CH_3)C_6H_4OH), were prepared and characterized by elemental and thermal analyses, molar conductance, infrared, ESR and electronic spectral studies. Some of the complexes were screened against E. coli and Aspergillus niger for biological activity.
