A novel coordination polymer 1 with formula of Zn₂(BDC)₂(TPPA) was built from 1,4-dicarboxy- benzene (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 with a = 14.589, b = 14.606, c = 16.108 Å, α = 115.635^o, β = 90.328^o, γ = 114.662^o, V = 2738.6 ų, Z = 2, M_r = 935.52 g/mol, D_c = 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.
