[Synthesis and spectroscopic analysis of complex Eu(o-ClC6H4OCH2COO)3.2,2'-bipy].

This work has synthesized a title complex using rare earth ion Eu3+ with the o-chlorophenoxyacetic acid and 2,2'-bipyridine. The chemical formula of the complex was determined to be Eu(o-ClC6H4OCH2COO)3.2,2'-bipy by elemental analysis, analysis of IR, UV, fluorescence spectra. The ternary turopium complex display intense fluorescence, the intensity of 5D0-->7F2 line in much higher than that of the 5D0-->7F1 line, which shows low symmetry of the Fe3+ ion site in the complex.
