摘要

Compound [Cd1.5(ppt)Br2(H2O)]2n (1), where Hppt = 3-(pyridin-4-yl)-5-(pyrazin- 2-yl)-1H-1,2,4-triazole, has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectra, powder XRD, and X-ray diffraction. Compound 1 crystallizes in the triclinic system, space group P with a = 7.4402(6), b = 8.0570(7), c = 12.8674(11) Å,  = 89.7300(10),  = 89.8570(10),  = 68.3910(10), V = 717.13(10) Å3, Z = 1, Dc = 2.638 g/cm3, μ = 7.824 mm1, F(000) = 534, the final R = 0.0324 and wR = 0.1084 for 2324 observed reflections with I > 2(I). X-ray diffraction analyses revealed that complex 1 is a 2D layered coordination polymer constructed from the linkage of [Cd3(μ-Br)4] trinuclear units with ppt spacers, and a 3D supramolecular architecture is further assembled in 1 via hydrogen-bonding contacts. Fluorescence measurements show that 1 has medium fluorescent emission at 450 nm.
