| Abstract: A europium coordination polymer [Eu(2,4-DClBA)3(CH3CH2OH)2]n(2,4-DClBA=2,4-dichlorobenzoate) was prepared by solvent method and its structure was determined by X-ray diffraction single-crystal structure analysis. The complex crystallizes in triclinic crystal system, P1 space group. The title complex is a infinite 1D chain polymeric structure through oxygen atoms of bidentate-bridging 2,4-DClBA anions linking up the neighboring central Eu3+ ions. Each Eu3+ ion is eight-coordinated with four oxygen atoms of four bidentate-bridging 2,4-DClBA anions, two oxygen atoms of one bidentate-chelating 2,4-DClBA anion and two oxygen atoms of two ethanol molecules. This complex exhibits strong red fluorescence radiated by ultraviolet light and the fluorescence spectrum has five peaks at 580, 593, 619, 652 and 699 nm corresponding to 5D0 → 7FJ (J=0～4) transitions of the Eu3+ ion. CCDC: 667995. |
