Salicylaldehyde(N-benzoyl)glycyl hydrazone (SalBzGH) has been synthesized and characterized.Metal complexes of the empirical formula where Ln = Y, Pr, Nd, Sm, Eu, Gd and Dy, have been synthesized and their structures studied by infrared, far-infrared, absorption, emission and NMR spectra. 1H and 13C NMR spectra indicate the presence of dynamic equilibrium between two isomers of SalBzGH over the 298-368 K temperature range and stabilization of a single isomer upon complexation with Ln(III).The hypersensitive band profile of the Nd(III) complex indicates a change in metal coordination number due to solvation, while an increase of temperature results in a decrease of εmax of the hypersensitive band.The emission spectrum of at 77 K indicates a low site symmetry.SalBzGH coordinates through imidolic oxygen, azomethine nitrogen and phenolate oxygen.
