Abstract
An interesting metal-organic network with helical motifs, {[Zn2(mpdc)2(bpy)(H2O)2] · 2H2O} (1, mpdc = 2,6-dimethyl pyrdine-3,5-dicarboxylate), was synthesized under hydrothermal conditions, and characterized. Single-crystal X-ray structural analysis indicates that the title compound crystallizes in a monoclinic lattice, P2(1)/c with a = 7.811(2), b = 12.324(3), c = 15.794(4)A, β = 98.206(4)°, Z = 2, V = 1504.8(7) Å3, D c = 1.704 Mg m−3, F(000) = 816, R 1 = 0.0379, wR 2 = 0.0807. In the structure of 1 the helical strands composed of [Zn(mpdc)(H2O)] array in an interlacing fashion, and trap solvated water molecules to assemble a novel supramolecular network. Compound 1 exhibits strong photoluminescence in the solid state at room temperature.
