摘要
A two-dimensional（2D） coordination polymer {[Cd2（sdb）2（dpb）2]·3H2O}n（1） was prepared by solvothermal reaction of two types of V-shaped ligands： 1,3-dipyridyl benzene（dpb） and deprotonated 4,4＇-sulfonyldibenzoic acid（H2sdb）. It was characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Complex 1 crystallizes in the monoclinic system, space group Fdd2 with a = 46.247（10）, b = 9.994（2）, c = 24.267（6） A, V = 11216（4） A3, C60H46Cd2N4O15S2, Mr = 1387.97, Dc = 1.559 g/cm^3, F（000） = 5296.0, μ = 0.902 mm^-1 and Z = 8. Each [Cd（COO）]2 cluster links four sdb2- anions to form infinitely ABAB stacked 2D wave-like sheets, in which each sheet contains the same helical chains, and the helical directions of sheets A and B are reversed. Dpb links the rest coordinated sites of [（COO）Cd]2 cluster to form a 2D network. In addition, the solid fluorescence of 1 and dpb is also studied.
