| 摘 要： | A binuclear zinc（Ⅱ） complex with 2-carboxycinnamic acid （2-ccm） and dipyrido- 3,2-a：2＇,3＇-c]phenazine （DPPZ）, {Zn2（2-ccm）2（DPPZ）2]·2H2O}n, was synthesized and characterized by elemental analysis, IR, single-crystal X-ray diffraction, thermal gravimetry and fluo- rescent emission. It crystallizes in monoclinic, space group P21/c with a = 13.409（4）, b = 25.530（7）, c = 13.952（4） A, β = 99.554（3）°, V= 4710（2） A3, Z= 4, C56H36N8O10Zn2, Mr= 1111.67, Dc = 1.568 g/cm3, μ（MoKα） = 1.093 mm^-1, F（000） = 2272, R = 0.0422 and wR = 0.0895. In the crystal, the basic unit of 1 is a binuclear Zn2 entity which is linked by 2-ccm ligand to form a 1D double chain along the a axis. The O-H...O hydrogen bonding and π-π interactions lead to a 3D supramolecular motif. In addition, thermal and luminescent properties of complex 1 have also been investigated.
