A novel coordination polymer 1 with formula of Zn2(BDC)2(TPPA) was built from 1,4-dicarboxybenzene (H2BDC),tris(4-(pyridin-3-yl)phenyl)amine (TPPA),and Zn(Ⅱ) ion.It was characterized by single-crystal and powder X-ray diffraction,Fourier-transform infrared spectra (FT-IR),thermal gravimetric analysis (TGA),and UV-vis.1 crystallizes in triclinic space group P(1) with a =14.589,b =14.606,c =16.108 (A),α =115.635°,β =90.328°,γ =114.662°,V=2738.6 (A)3,Z =2,Mr =935.52 g/mol,De =1.134 g/cm3,F(000) =956,GOOF =1.062,the final R =0.0685 and wR =0.1817 for 7701 observed reflections with (I ＞ 2σ(I)),and R =0.0717 and wR =0.1843 for all data.In 1,Zn(Ⅱ) is coordinated with H2BDC to form a 2D square grid,and TPPA ligands were arranged above and beneath the 2D layer.Two neighbor layers are interpenetrated each other by π-π interactions to generate a polythreading framework structure.Moreover,the photoluminescence of 1 was also studied.
