摘　　要：By using solvothermal method,a one-dimensional chain compound[KEu_(2)(FDCA)_(3)(H_(2)O)_(9)·0.5(FDCA)](1)was synthesized.Single-crystal X-ray diffraction data reveal that 1 crystallizes in monoclinic system,space group P21/n with a=12.1996(1),b=18.6454(2),c=17.7123(2)Å,β=98.8460(10)°,Dc=1.753 g/cm3,Z=2,V=3981.03(7)Å3,R=0.0544 and wR=0.1511 for 7886 observed reflections with I>2σ(I).In 1,three FDCA2–ligands construct a“23-crown-9-like”structure as the second building units(SBUs)to further form an infinite 1D chain.Meanwhile,the fluorescent result reveals that compound 1 can selectively and sensitively sense Fe^(3+)by the fluorescence quenching.
