Studies on the Rare Earth Coordination Compounds(Ⅶ)—Synthesis and Characterization of Coordination Compounds of Rare Earth Element swith1,6-Bis(1'-phenyl-3'-methyl-5' -pyrazolone-4' -)-1,6-hexanedione

Abstract

Abstract: Fourteen solid coordination compounds of title compound(BPMPHD) with rare earths were synthesized from aqueous ethonal solution. Elemental analysis agree with proposed stoichiometric RE₂A₃.4H₂O (where RE = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb. A = C₂₆H₂₄N₄O₄^2-). The compounds were characterized by UV, IR, molar conductance, fluorescence spectra and thermoanalysis. The dinuclear structures of these complexes were confirmed by X-ray powder diffraction.

Key words: Rare earth elements, 1, 6-Bis(1'-phenyl-3'-methyl-5' -pyrazolone- 4' )-1, 6-Hexanedione, Coordination compound
