Abstract: Sixteen cornplexes of rare earth (RE=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y) with 1-pheny-3-methyl-4-benzoyl-pyrazolone-5 (HPMBP) and 1-nitroso-2-naphthol (NN) have been synthesized and characterized by elemental analysis, IR 1HNMR and DTA measurements. The ternary complexes have a general formula RE:PMBP:NN=1:3:1(1:4:1 when RE=Ce(Ⅳ)). All the complexes are crystal in gray-violet colour. They are soluble in ethanol, acetone and benzene, insoluble in water, and air-stable at room temperature.

Key words: rare earth, phenylmethylbenzoylpyrazolone, nitrosonaphthol, ternary complex, synthesis
