Synthesis and Structural Characterization of a New 3D Lead Coordination Polymer with a Tetrazole-1-acetate Ligand

One new lead coordination polymer, [Pb(tza)<,2>]<,n>(1, Htza=tetrazole-1-acetic acid)has been synthesized under hydrothermal conditions and characterized by elemental analysis, IRspectroscopy, thermogravimetric analysis (TGA), fluorescence spectra and single-crystal Ⅹ-ray diffraction. Coordination polymer 1 is of monoclinic system, space group C2/c with a =15.4388(16), b = 10.4039(11), c = 8.3360(8) A,β= 119.2070(10)°, V= 1168.7(2) A<'3>, C<,6>H<,6>N<,8>O<,4>Pb,Z= 4, Mr = 461.38, Dc = 2.622 g/cm<'3>,μ(MoKa) = 14.463 mm<'-1>, F(000) = 848, the final R = 0.0373and wR = 0.0904 for 2744 observed reflections with Ⅰ>2σ(Ⅰ). 1 is a 3D coordination framework built from Pb-carboxylate chains and the tetrazole nitrogen atoms of tza ligands. Furthermore, the luminescent property of 1 has also been investigated.
