摘要：

A new dinuclear complex [Zn(dpa)(bipy)(H2O)](2) (dpa = 2,2'-diphenic acid, bipy = 2,2'-bipyridine) 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. The complex crystallizes in monoclinic, space group P2(1)/c with a = 10.960(2), b = 9.4841(18), c = 20.599(4) angstrom, beta = 104.452(3)degrees, V = 2073.4(7) angstrom(3), C48H36N4O10Zn2, M-r = 959.55, D-c = 1.537 g/cm(3), mu(MoK alpha) = 1.225 mm(-1), F(000) = 984, Z = 2, the final R = 0.0364 and wR = 0.0843 for 2788 observed reflections (I > 2 sigma(I)). In the crystal structure, the zinc atom is five-coordinated with two carboxylate oxygen atoms from different dpas, one coordinated water molecule and two nitrogen atoms from bipy ligands, showing a slightly distorted triangular bipyramidal geometry. Furthermore, it exhibits a zero-dimensional network structure with a sixteen-membered ring and shows yellow photoluminescent property at room temperature.
