摘要	Two binuclear europium. complexes [Eu-2(SA)(6)(Phen)(2)].6H(2)O (1) and [Eu-2(SA)(4)(phen)(2)(H2O)(4)](ClO4)(3) (phenH).H2O (2) (where SA = succinamate, phen = 1,10-phenanthroline) have been synthesized and characterized by X-ray single crystal diffraction. For 1, the unit cell contains two crystallographically independent Eu(SA)(3)(phen) species in which the Eu3+ ions have two different coordination environments. Two types of binuclear molecule are arranged in different orientations in the crystal. The F-7(0) --> D-5(0) excitation peaks at 580.16 and 580.46 nm at 77 K and the Stark components of D-5(0) --> F-7(J) transitions, especially D-5(0) --> F-7(1) and D-5(0) --> F-7(2) emission lines, show that complex 1 has two Eu(III) ion sites, which is in good agreement with the results of the structure determination. In complex 2, four water molecules take the place of two bidentate chelating SA anions in the inner coordination sphere of 1. Outside the coordination sphere, the protonated phen molecule forms a hydrogen bond with a tridentate-coordinated carboxyl group and has a pi-pi stacking interaction with the coordinated phen molecule.
