Abstract The rare earth complexes of 1-(2-pyridylazo)-2-naphthol (PAN=Hpan) are prepared in the solid state. The analytical, molecular weight and differential thermal analysis data of the complexes indicated the metal-ligand ratio as 1:3 with the general formulae Ln(pan)3·H2O (Ln=Pr3+, Nd3+, and Sm3+) and Ln(pan)3 (Ln=La3+, Eu3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, and Yb3+). Based on IR, UV, and visible absorption spectra, electrical conductance and magnetic susceptibility data, an octahedral structure having the metal ion bonded through nitrogen of azo and oxygen of carbonyl groups of the ligand has been postulated to these complexes.
