Abstract
2-Aminobenzophenonesalicylaldazine (Habs) reacts with metal(II) acetate and yields the complexes M(abs)2(H2O)2 [M = Mn(II), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II)]. The complexes were characterized by elemental analyses, molar conductance, molecular weight, magnetic susceptibility, electronic, ESR, IR and NMR spectral data. The electrical conductivity shows the non-ionic nature of the complexes. The magnetic moment and electronic spectra suggest octahedral stereochemistry for the cobalt(II) and nickel(II) complexes. ESR data suggest tetragonal distortion in the copper(II) complex having dx 2 - y2 ground state. Infrared spectra suggest bonding through the phenoxy oxygen and azomethine nitrogen in the Co(II), Ni(II) and Cu(II) complexes and only the phenoxy oxygen in the Mn(II), Zn(II) and Cd(II) complexes which is also supported by NMR spectral studies.
