The compound crystallizes in the monoclinic system, space group C2/c with a=13.7866（6）, b=10.1557（4）, c=30.9036（17）, β=101.422（5）o, V=4241.2（3）3 , Z=4, Dc=1.547g/cm3 , Mr=987.94, F（000）=2056, μ（MoKα）=1.078 mm-1 , S=1.007, R=0.0453 and wR=0.987 for 2806 observed reflections （I〉2σ （I））. The title compound is characteristic of the cyclic dimeric molecules which further aggregate through hydrogen bonds and π-π interactions to form a 3-D supramolecular network. The microbial activities of the title compound and its reagents are investigated with filter paper discs diffusion method. The results show that the activity of the title compound is slightly better than its precursor reagents.展开更多
A new complex Eu2（PA）6（phen）2 was prepared with hydrothermal reaction using EuCl3.6H2O, phenylmalonic acid （H2phma）, and 1, 10-phenanthroline （phen）, where PA was the decarboxylated product of HEphma, phenylac...A new complex Eu2（PA）6（phen）2 was prepared with hydrothermal reaction using EuCl3.6H2O, phenylmalonic acid （H2phma）, and 1, 10-phenanthroline （phen）, where PA was the decarboxylated product of HEphma, phenylacetate. The crystal structure of the title complex was determined with the X-ray diffraction. The title complex was a binuclear molecule with an inversion center. Each Eu^3＋ ion was nine-coordinated with two nitrogen atoms from one phen molecule and seven oxygen atoms from five PA ligands. The carboxylic groups were bonded to the Eu^3＋ ion in three modes, the chelating bidentate, the bridging bidentate, and the bridging-chelating tridentate. The complex emits intense red fluorescence under ultraviolet light. The luminescence peaks correspond to the characteristic emission 5D0→7FJ （J=0-4） transitions of the Eu^3＋ ion.展开更多
