摘 要：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 H2phma, 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 Eu3+ 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 Eu3+ ion in three modes, the chelating bidentate, the bridging bidentate, and the bridging-chelating tridentate. The com- plex emits intense red fluorescence under ultraviolet light. The luminescence peaks correspond to the characteristic emission 5D0→7FJ （J=0-4） transitions of the Eu3+ ion.
