摘　　要：合成了一种新颖的配合物[Zn(H2O)(bpp)(Bript)2]n(其中,bpp=1,3-二(4-吡啶)丙烷,H2Bript=5-溴间苯二甲酸),并用X-射线单晶衍射仪测定了其结构.晶体数据表明,该配合物属单斜晶系,空间群P21/c,晶胞参数为:a=7.862(3),b=27.530(10),c=9.664(4),β=96.694(6)°,V=2077.6(13)3,Z=4,Dcalc=1.677 g·cm-3,μ=3.141 mm-1,F(000)=1056,R1=0.1119,wR2=0.2760.在配合物中,Zn原子被5-溴间苯二甲酸离子连接为一维链,这些一维链通过氢键和π…π相互作用连接在一起形成二维超分子化合物.A new coordination compound [ Zn （ H2O） （bpp） （Bript） 2 ] n （ where bpp = 1,3-bi （4-pyridyl） pro- pane,H2Bript = 5-bromoisophthalic acid） has been synthesized. The crystal structure of the compound was deter- mined by X-ray single crystal diffraction. As the data indicate, its crystal belongs to monoclinic system with space group P21/c, a = 7.862（3） A, b = 27.530（10） A, c = 9.664（4）A, β = 96.694（6） °, V = 2077.6（13）A^3, Z = 4, Dcac= 1.677 g·cm^-3,μ = 3. 141mm^1, F（000） = 1056, R1 = 0.1119, wR2= 0.2760. In the compound, Zn （Ⅱ） atoms are linked by Bript to form a ID chain. These ID chains are further linked by hydrogen bonds interactions and -π...πinteraction to generate to a two-dimensional structure. The thermal stability of the title complex has been briefly investigated.
