摘要 | The title complex, C55H41O6N2Eu, M(r)=979.91, crystallizes in the monoclinic space group C-2k with a=2.0413(4), b=2.5556(5), c=0.8926(3)nm, beta=104.64(2)degrees, mu=14.44cm(-1), T=295K and the final R=0.043. The structure was solved by the heavy-atom method and refined by the full-matrix least-squares technique For 64 non-hydrogen atoms anisotropically for 2180 reflections with 1 greater than or equal to 3 sigma(I). The title complex forms one-dimensional chains through C-C bonds between pyridine rings of 4,4'-bipyridine. The central Eu(III) ion is coordinated to six oxygen atoms and two nitrogen atoms and its polyhedron is a distorted square antiprism. The high resolution laser excited excitation and luminescence spectra show that the complex possesses two Eu(III) sites with the energy difference 39cm(-1) of D-5(0) levels in excited state. The radiationless energy transfer to a great extent between the two Eu(III) sites and the dominant luminescence of Eu(III) site with lower energy as the complex was excited have been supported by the selectively excited luminescence spectra, time-resolved luminescence spectra acid selectively excited luminescence decay curves. |
