Abstract

The present work describes the synthesis and characterization of some six and nine coordinated complexes of trivalent lanthanide(III) with 4[N-(2´-hydroxy-1´- naphthalidene)amino]antipyrinethiosemicarbazone (HNAAPTS). All the complexes have the general composition LnX3.n(HNAAPTS) (X = NO3-, n = 1; X = NCS- or ClO4-, n = 2). The complexes were characterized through elemental analyses, molar mass, conductivity measurements, magnetic susceptibilities, and infrared and electronic spectra. Infrared spectra revealed that HNAAPTS acts as a neutral tridentate (N,N,S) donor. The coordination number in these complexes is either six or nine depending on the nature of the anionic ligand.
