Synthesis, Structure and Photoluminescence of a Tetranuclear Zinc（II） Complex： Zn4（SO4）2（DPPZ）4（HSal）2（OH）2

摘要

cqvip:A new tetranuclear zinc(Ⅱ) complex [Zn4(SO4)2(DPPZ)4(HSal)2(OH)2] 1 (DPPZ = dipyrido[3,2-a:2',3'-c]phenazine, H2Sal = salicylic acid) was prepared by using hydrothermal syn- thesis and characterized by elemental analysis, IR spectrum, thermal gravimetry (TG), fluorescent emission and single-crystal X-ray diffraction. Its crystal structure is of monoclinic, space group P21/c with a = 9.8897(8), b = 14.2506(12), c = 26.384(2) , β = 94.8940(10)°, V = 3704.8(5) 3, Z = 2, C86H52N16O16S2Zn4, Mr = 1891.04, Dc = 1.695 g/cm3, μ = 1.423 mm–1, F(000) = 1920, GOOF = 1.039, the final R = 0.0358 and wR = 0.0872 for 6038 observed reflections with I > 2σ(I). In 1, "cage-like" tetranuclear clusters of [Zn4(SO4)2(DPPZ)4(HSal)2(OH)2] are further stacked through π-π interactions to generate a 3D supramolecular network.
