| 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 charac-terized 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(MoKa) = 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 ID double chain along the α 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.
