| Abstract: The coordination polymer [Eu2(C10H9NO2)6(H2O)2]n with o-acetamidobenzoic acid and 1,10-phenanthroline has been synthesized by means of hydrothermal way and characterized. It crystallizes in the monoclinic space group P21/n, with a=1.074 19(10) nm, b=1.063 39(9) nm, c=2.496 7(2) nm, β=100.2610(10)°. The crystal structure shows that four bi-dentate bridging o-acetamidobenzoic acid groups and two europium(Ⅲ) ions form a binuclear cage structure in [Eu2(C10H9NO2)6(H2O)2]n, where the distance between Eu(1) and Eu(1A) is 0.428 9 nm. Two neighboring cage structures are linked together by two o-acetamidobenzoic acid and the complex molecule forms an one-dimensional chain structure. In the complex, the europium(Ⅲ) ion is coordinated with eight oxygen atoms from seven o-acetamidobenzoic acid molecules and one water molecule, forming a distorted square antiprism coordination geometry. The luminescence property of the complex was also studied. CCDC: 674226. |
