Abstract: | Summary
o-Hydroxyacetophenone (N-benzoyl)glycyl hydrazone (o-HABzGH) has been characterized by i.r.,1H n.m.r.,13C n.m.r. and mass spectral studies, and its complexes of the types Ln(o-HABzGH)Cl2(H2O)2]Cl and Ln(o-HABzGH–2H)OH(H2O)3], where Ln=La, Pr, Nd, Sm and Eu, have been synthesized. The structures of the complexes have been studied by conductance, magnetic, electronic, i.r.,1H n.m.r. and13C n.m.r. spectral techniques. The hypersensitive bands of the electronic spectra suggest coordination numbers six and seven around NdIII in its adduct and neutral complexes respectively. I.r. and n.m.r. spectral data suggest a neutral bidentate behaviour for the ligand in the adducts and a dinegative tridentate nature in the neutral complexes. |
