CHELATION OF 2-AMINOBENZOPHENONE-2-FUROYLHYDRAZONE WITH SOME BIVALENT-METAL IONS - MAGNETIC AND SPECTRAL STUDIES

Reaction of 2-aminobenzophenone-2-furoylhydrazone (Habfh) with metal s alts yields complexes of the chemical compositions VO(Habfh)2SO4, M(Ha bfh)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 acetoni trile and dimethylformamide solution. The electronic structures of the complexes have been studied by magnetic susceptibility, electronic, p hotoacoustic and esr spectral studies. Infrared and n.m.r. spectra hav e 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.
