Abstract: The present paper covers fifteen new solid complexes of rare earth synthsized by the reaction of rare earth nitrates and (NH4)2Ce(SO4)3 with BPMPPD in the aqueous solution of ethanol.The compounds with a general formula: RE2(BPMPPD)3·nH2O(Re= La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Y.n = 3-7) ,Ce(BPMPPD)2·6H2O and (Y-Eu)2·(BPMPPD)3·8H2O(Y:95%; Eu: 5%), were obtained and characterized by elemental analysts, chemical analysis, IR, DTA-TG, 1H NMRand fluorescence.

Key words: 1,5-Bis-(1'-phenyl-3'-methyl-5'-pyrazolone-4')-pentanedione-(1,5) (BPMPPD), Rare earth, Fluorescence
