摘要A novel compound, {[Y(HPIDC)(OX)1/2(H2O)]·2H2O}n (1, H3PIDC = 2-(pyridin-4- yl)-1H-imidazole-4,5-dicarboxylic acid, H2OX = oxalic acid), has been synthesized under hydrother- mal conditions and characterized by thermal analysis (TGA), powder X-ray diffraction (PXRD), and single-crystal X-ray diffraction. Complex 1 crystallizes in monoclinic space group P21/c with a = 8.342(8), b = 14.61(1), c = 11.487(1) Å,β =90.78(9)°, V =1400.4(2) Å3,Z = 4, C11H11N3O9Y, Mr=418.14, Dc =1.983 g/cm3,F(000) = 836, Rint = 0.0509, T = 293(2) K, μ = 4.240mm−1,the final R = 0.0477 and wR = 0.1125 for 2770 observed reflections with I > 2σ(I). Compound 1 exhibits a 3D framework and generates the 1D open channels filled with free water molecules. The structure of 1 can be rationalized as a diamondoid network when the atom yttrium is regarded as a 4-connected node linking four surrounding yttrium atoms. The luminescent property of compound 1 is also investigated.
