摘要
A novel europium(III) complex, [Eu(C7H5O2)(2)(C7H6O2)(2)(C12H8N2)(2)Cl], was synthesized and characterized by elemental analysis and single-crystal X-ray determination. It crystallizes in the monoclinic system, space group Cc with a = 17.2814(16), b = 17.9421(17), c = 14.9971(14) , beta = 101.6510(10)A degrees, Z = 4, rho (c) = 1.508 g/cm(3), mu = 1.496 mm(-1), the final R = 0.0516 and wR = 0.1267 for 6435 observed reflections with I > 2 sigma(I). Structural analysis shows that the Eu(III) atom is nine-coordinated by one chlorine atom, four N atoms of two 1,10-phenanthroline (Phen) ligands, and four O atoms from four carboxybenzene ligands, to form a distorted tricapped trigonal prism. The luminescence spectrum of the complex indicates that the intensity of the emission wavelength at 612 nm is strongest among all emission wavelengths and the second phen ligand shows an enhancement effect on the luminescence of the complex.
