      Some trivalent lanthanide complexes of acetone isonicotinoylhydrazone (AINH), having the empirical formula Ln(AINH)3Cl3, where Ln=La(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III), Dy(III) and Y(III) were prepared. Elemental analyses, molar conductance, magnetic susceptibility, IR, electronic,1H,13C and139La NMR spectra of the complexes have been examined. It has been found that AINH behaves as a neutral bidentate ligand coordinating through the carbonyl oxygen and azomethine nitrogen. Temperature-dependence of the molar absorptivity and the metal coordination number has been established by the electronic spectra of Nd(AINH)3Cl3 recorded over the 28–80°C range.
