A Zn(Ⅱ) Coordination Polymer with 4-Connected bbf Topology: Synthesis,Crystal Structure and Luminescent Property

A new Zn(Ⅱ) compound, namely {Zn(BTA)(pdc)_(0.5)}_n(1, HBTA = 1,2,3-benzotriazole, H_2pdc = terephthalic acid), has been hydrothermally synthesized and characterized by elemental analysis, infrared analysis, powder X-ray diffraction analysis and single-crystal X-ray structural analysis. The crystal structure is of monoclinic system, space group P21/c with a = 10.751(3), b = 9.792(3), c = 9.292(3) ?, β = 95.391(4)°, V = 973.9(5) ?3, C10H6N3O2 Zn, Mr = 265.57, Z = 4, Dc = 1.811 g/cm3, F(000) = 532, μ = 2.506 mm-1, R = 0.0221 and w R = 0.0605 for 2075 observed reflections(I 2s(I)). Single-crystal X-ray structural analysis reveals that compound 1 features a three-dimensional(3D) framework with 4-connected bbf topology. Moreover, the thermogravimetric(TG) analysis and photoluminescent property of 1 were also discussed.
