摘要
A novel coordination polymer 1 with formula of Zn_(2)(BDC)_(2)(TPPA) was built from 1,4-dicarboxybenzene (H_(2)BDC),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 P1 with a=14.589,b=14.606,c=16.108?,α=115.635~o,β=90.328~°,γ=114.662~o,V=2738.6A^(3),Z=2,M_(r)=935.52 g/mol,D_(c)=1.134 g/cm~3,F(000)=956,GOOF=1.062,the final R=0.0685 and w R=0.1817 for 7701 observed reflections with (I>2σ(I)),and R=0.0717 and w R=0.1843 for all data.In 1,Zn(Ⅱ) is coordinated with H_(2)BDC to form a 2D square grid,and TPPA ligands were arranged above and beneath the 2D layer.Two neighbor layers are interpenetrated each other byπ-πinteractions to generate a polythreading framework structure.Moreover,the photoluminescence of 1 was also studied.
