Abstract
Reaction of 2-aminobenzophenone-2-furoylhydrazone (Habfh) with metal salts yields complexes of the chemical compositions VO(Habfh)2SO4, M(Habfh)2Cl2 and M(abfh)2 [M = OV(IV), Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II)]. The complexes are non-electrolytes in acetonitrile and dimethylformamide solution. The electronic structures of the complexes have been studied by magnetic susceptibility, electronic, photoacoustic and esr spectral studies. Infrared and n.m.r. spectra have been used to ascertain the ligational properties of Habfh. An X-ray diffraction study has been used to elucidate the shape and size of the unit lattice of copper(II) and zinc(II) complexes.
