摘要：
New complexes of hydrated lanthanide(III) nitrates with 2,6-bis(benzimidazol-2'-yl)pyridine (BBP) having the formulae [Ln(BBP)2(NO3)2]NO3 . nH2O (where Ln = La-Nd, Sm-Tb, n = 1, 2), [Ln(BBP)(BBP-H)(NO3)(OH2)]NO3 . nH2O (where Ln = Dy, Er, n = 3,4) and (Ln(BBP-H)(NO3)2(OH2)] . 2H2O (where Ln = Lu) have been prepared and characterized by elemental analyses, IR and electronic spectra, molar conductance, thermal analyses and X-ray powder diffraction patterns. The emission spectra of all the complexes have also been examined. It has been found that all the complexes show the luminescence of the ligand. The Sm, Eu and Tb complexes also show the corresponding metal ion luminescence.
