摘要：

One new rare-earth ternary complex with 1-naphthylacetic acid and 1,10-phenanthroline, [Eu0.5Gd0.5(C12H9O2)(2)(C12H8N2)(2)(H2O)(2)]center dot(C12H9O2)center dot H2O were synthesized. The structures were established by single crystal X-ray diffraction. The europium (gadolinium) ion is eight-coordinate with four oxygen and four nitrogen atoms forming a coordination polyhedron best describable as a distorted dodecahedral. The luminescence spectra of the complex in a solution of DMF were studied. The complex display characteristic Eu(III)-originated red emission as a sharp band at 617 nm. It is concluded that the metal-centered red emission is promoted by the ligand-assisted energy transfer.
