摘要:

Nine new lanthanide complexes, [Ln(OPPh3)(2)(phen)(NO3)(3)] (1-5) (OPPh3 = triphenylphosphine oxide, phen = 1,10-phenanthroline, Ln = Ce, Gd, Tb, Ho, Eu) and [Ln(OPPh3)(2)(C2H5OH)(NO3)(3)] (6-9) (Ln = Tb, Ho, Er, Tm), have been synthesized by the reactions of lanthanide nitrates, the OPPh3 ligand and phen in acetonitrile (1-4) or ethanol (5-9) in the air. These title complexes were characterized by IR, elemental analyses, single-crystal X-ray diffraction analysis, luminescence, thermogravimetric analysis, H-1 NMR and P-31 NMR spectroscopy. Structure analysis shows complexes 1-9 consist of one Ln(3+) cation and three NOi anions, with the Ln ion being ten-coordinated (1-5) or nine-coordinated (6-9). In complexes 1-5, two forms of pi center dot center dot center dot pi interactions exist between the phen rings and benzene rings from the OPPh3 ligand. Robust R-2(2)(12) hydrogen bonds exist in complexes 6-9. Solid luminescence spectra of compounds 5, 3 and 6 are assigned to the emission of Eu3+, Tb3+. The emission lifetimes (1.14 ms of D-5(0) for compound 5, 1.10 and 0.97 ms of D-5(4) for compounds 3 and 6) and absolute emission quantum yields (26.88% for compound 5, 11.36% and 2.16% for compounds 3 and 6) were also determined.
