Abstract: The ternary complexes of rare earth salicylate(Sal)with 2,2′-bipyridine-N,N′-dioxide(biPyO2)having composition RE(biPyO2)(Sal)3(for RE=La, Ce)and RE(biPyO2)(Sal)2Cl(for RE=Pr, Nd, Sm, Eu)were prepared. The complexes have been characterized by in-frared spectrometry,thermogravimetry, differential scanning calorimetry and fluorescent spec-troghotometry.

Key words: light rare earth, bipytridine dioxide, salicylic acid, ternary complex
