A cyclic bimetallic metal-organic complex [Zn(Cl)(H-fmpdc)(H2O)](2)center dot 2H(2)O (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) angstrom, V = 3029.4(10) angstrom(3), Z = 4, D-c = 1.644 g/cm(3), F(000) = 1616, R = 0.0347 and wR = 0.0956 (I > 2 sigma(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 H(2)fmpdc ligand. The title compound 1 shows strong photoluminescence with emission maximum at lambda = 402 nm (lambda(ex.max) = 367 nm).
