| 摘 要： | Under hydrothermal condition, the reaction of 2-naphthoxyacetic acid with ZnCl2 and 4,4'-bipyridine (4,4'-bipy)has afforded a new Zn(Ⅱ) compound,[Zn(C12H9O3)2(C10H8N2)]n·nH2O1, which was structurally characterized by single-crystal X-ray diffraction analysis. The crystal is of monoclinic, space group P21/c with a = 7.7335(2), b = 19.3834(4), c = 20.1707(4) (A), β =104.9830(10)°, V = 2920.82(11) A3, C34H28ZnN2O7, Mr = 641.95, Z = 4, Dc = 1.460 g/cm3, μ = 0.895 mm-1, F(000) = 1328, R = 0.0406 and wR = 0.0876 for 4417 observed reflections (Ⅰ>2σ(Ⅰ)). Complex 1 consists of one-dimensional zigzag chains deriving from Zn(C12H9O3)2 units linked by 4,4'-bipy ligands, and lattice water molecules decorate between the chains. Non-covalent interactions, such as hydrogen-bonding and aromatic π-π interactions, lead to the formation of a 3D network structure. The thermogravimetric analysis (TGA) and luminescent property for 1 have also been studied in this paper.
