Compounds of formula Ln(tta) 3 (pp) and Y(tta) 3 (pp), where Ln = La-Yb except Ce, Pm and Tm, Htta = 3-(2-theonyl)-1,1,1-trifluoroacetone and pp = 1-phenylpiperazine, have been synthesized and characterised on the basis of stability, solubility, melting point, elemental analysis, molar conductance, IR and NMR spectra. 1-Phenylpiperazine is coordinated only through its NH nitrogen...
The emission spectra of several compounds of europium(III) incorporating a variety of β-diketonates and N-bases have been examined in order to obtain reliable information relating to coordination number, nature of bonding and symmetry around the lanthanide ion. It has been found that steric factors may force the polyhedron of coordination towards geometries less favorable by ligand-ligand repulsion...
