  N-(3,4-diaminobenzophenonimino)-2-benzamido-ethanamide, dabbe, has been synthesized and characterized. The ligand dabbe was found to coordinate with the trivalent lanthanide metal ions to give Ln(III) metal complexes of the type [Ln (dabbe)(2)Cl-3].4H(2)O where Ln=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy and Y. The complexes were studied by elemental analyses, electrical conductance, magnetic susceptibility, electronic, infrared and NMR (H-1 C-13 and La-139) spectral techniques. Various bonding parameters (beta, b(1/2), % delta and eta) were calculated from the electronic spectra of the Pr(III), Nd(III), Sm(III) and Dy(III) complexes and suggest weak covalent bond formation in the complexes. The theoretical oscillator strengths (P-calcd) and a set of three intensity parameters (T-lambda-2,T-4,T-6) computed from the Judd-Ofelt equation are found to be in reasonable agreement with the experimental values. An approximate mean M-L distance, R(Ln-O) Angstrom in case of the Pr(III) complex was found to be 2.56 Angstrom from the energy of the H-3(4)-->P-3(0) transition. IR and NMR spectral data suggest a neutral bidentate nature of dabbe in the complexes. Low site molecular symmetry in the present complexes is proposed on the basis of La-139 NMR spectra.
