摘　　要：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 synthesis 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 P2 1/c with a = 9.8897（8）, b = 14.2506（12）, c = 26.384（2） ,A, β = 94.8940（10）°, V = 3704.8（5） A3 Z = 2, C86H52N16O16S2Zn4, Mr = 1891.04, Dc = 1.695 g/cm^3, 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.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 synthesis and characterized by elemental analysis, IR spectrum, thermal gravimetry （TG）, fluorescent emission and single-crystal X-ray diffraction.
