Abstract

Abstract: This paper reports the preparation and properties of the complexes of rare earths with 1-phenyl- 3-metlfyl-4-benz6yl-pyrazolone-5 (HPMBP) and 1-nitroso-2-naphthol (NN).Compounds of general formulas RE(PMBP)₃(NN) (whereRE=La, Pr,Nd,Sm,Lu and Y)were obtained and characterized by elemental ana-lysis,IRspectra and ¹H NMR.All fourteen-complexes obtained are gray-violet crystal. They are soluble in ethanol, acetone and benzene, but insoluble in water. In atmosphere, these complexes are stable at room temperture.

Key words: 1-Phenyl-3-methyl-4-benzoyl-pyrazolone-5, 1-Nitroso-2-naphthol
