| 摘 要： | A novel two-dimensional coordination polymer [Ba2(phen)4(tp)2]n(phen=1,10-phenanthroline,tp=terephthalic acid) has been synthesized with tp as bridge ligands and structurally determined by X-ray crystallography.The crystal belongs to the monoclinic system,space group C2/c,with a=18.877(4),b=18.489(4),c=15.658(3),β=103.61(3)o,V=5311.5(19)3,C32H20O4N4Ba,Mr=661.86,Z=8,F(000)=2624,μ=1.542mm-1,Dc=1.655 g/cm3,the final R= 0.0228 and wR=0.0554 for 6063 observed reflections(I2σ(I)).The structural analysis shows that each tp ligand bridges barium atoms to form a two-dimensional infinite layer.There are aromatic π-π stacking interactions between neighboring layers,and aromatic π-π interactions further extend such layers into a three-dimensional supramolecular framework.

| Abstract: | A novel two-dimensional coordination polymer [Ba_2(pben)_4(tp)_2]_n (phen = 1,10phenanthroline, tp = terephthalic acid) has been synthesized with tp as bridge ligands and structurally determined by X-ray crystallography. The crystal belongs to the monoelinie system, space group C2/c, with α = 18.877(4), b = 18.489(4), c = 15.658(3)(A), β = 103.61(3)°, V= 5311.5(19) (A)~3,C_(32)H_(20)O_4N_4Ba, M_r = 661.86, Z = 8, F(000) = 2624,μ = 1.542 mm~(-l), D_c = 1.655 g/cm~3, the final R =0.0228 and wR = 0.0554 for 6063 observed reflections (I＞ 2σ(I)). The structural analysis shows that each tp ligand bridges barium atoms to form a two-dimensional infinite layer. There are aromatic π-π stacking interactions between neighboring layers, and aromatic π-π interactions further extend such layers into a three-dimensional supramoleeular framework. |
