| 摘 要： | A cyclic bimetallic metal-organic complex Zn（C）（H-fmpdc）（H2O）]2·2H2O （fmpdc = 4-（furan-2-yl）-2,6-dimethylpyridine-3,5-dicarboxylate） was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in orthorhombic, space group Pbca with a = 12.905（2）, b = 14.774（3）, c = 16.833（3）A, V= 3029.4（10）A^3 Z = 4, Dc = 1.644 g/cm^3, F（000） = 1616, R = 0.0347 and wR = 0.0956 （I 〉 2σ（I））. There exist diverse supramolecular motifs （1-D, 2-D and 3-D） from distinct hydrogen bonds in the crystal structure of the title compound. The furanyl group has obvious contribution to the red-shift in the photoluminescent spectrum of the H2fmpdc ligand. The title compound 1 shows strong photoluminescence with emission maximum at 2 = 402 nm （λex.max = 367 nm）.

| Abstract: | A cyclic bimetallic metal-organic complex Zn(Cl)(H-fmpdc)(H2O)]2·2H2O (fmpdc = 4-(furan-2-yl)-2,6-dimethylpyridine-3,5-dicarboxylate) was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in orthorhombic, space group Pbca with a = 12.905(2), b = 14.774(3), c = 16.833(3) (A), V = 3029.4(10) (A)3, Z = 4, Dc = 1.644 g/cm3, F(000) = 1616, R = 0.0347 and wR = 0.0956 (I > 2σ(I)). There exist diverse supramolecular motifs (1-D, 2-D and 3-D) from distinct hydrogen bonds in the crystal structure of the title compound. The furanyl group has obvious contribution to the red-shift in the photoluminescent spectrum of the H2fmpdc ligand. The title compound 1 shows strong photoluminescence with emission maximum at λ = 402 nm (λex-max = 367 nm). |
