Studies on Complexes of Co(II), Ni(II), Cu(II), and Cd(II) with Acetophenone and 4-Hydroxyacetophenone 4-Aminobenzoylhydrazones

Abstract: Metal(II) complexes of the types [M(L)2Cl2]·H2O and [Cu(4-HOABH)SO4(H2O)2] [M═Co(II), Ni(II), Cu(II) and Cd(II), L=acetophenone benzoylhydrazone (ABH), C6H5CONHN = C(CH3)C6H5 and 4-hydroxyacetophenone benzoylhydrazone (4-HOABH), C6H5CONHN = C(CH3)C6H4OH], 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.

Studies on complexes of cobalt(ii), nickel(ii), copper(ii), and cadmium(ii) with acetophenone and 4-hydroxyacetophenone oxaloyldihydrazones

Abstract: The complexes [M(L1)nCl2] and [Cu(L2)SO4(H2O)2] [M= Co(II), Ni(II), Cu(II) and Cd(II); L1=acetophenone oxaloyldihydrazone (CONHN═C(CH3)C6H5)2, n=2 and L2=4-hydroxyacetophenone oxaloyldihydrazone (CONHN= C(CH3)C6H4OH–4)2 have been prepared. Analytical, molar conductance, magnetic susceptibility, electronic, ESR and NMR spectral data have been used to investigate the structure and bonding of the complexes. X-ray powder diffraction data indicate the shape and size of the unit cell of the copper(II) complex. Some of the complexes were screened against E. coli and Aspergillus niger for biological activity.
