摘　　要：以六钨酸盐(W6O129-)和1,4-双(咪唑-1-基)-丁烷(bbi)为混合配体,水热合成了一种新的三维超分子化合物[(W6O19)(H2bbi)](1),并通过红外、热重和单晶X-射线衍射法对其结构进行了表征。结果表明,该化合物属单斜晶系,C2/m空间群,晶胞参数为:a=15.1581(17),b=16.132(2),c=9.7379(12),β=96.293(1)0,V=2133.0(4)3,Z=2,R1=0.0772,wR2=0.2246。化合物1的基本构筑单元是质子化的配体bbi与多阴离子,在相邻构筑单元之间的氢键作用下化合物1最终拓展成为三维超分子网络结构。A new 3D supramolecular compound, [（W6O19）（H2bbi）]（1） [bbi = 1.1＇- （1,4--butanediyl）bis （imidazole）], has been obtained from hydrothermal reaction, and structurally characterized by IR, TG and single--crystal X--ray diffraction. Result reveals that compound 1 belongs to monoclinic system with C2/m space group. The cell parameters are： a = 15. 1581（17）A , b = 16. 132 （2）A , c = 9. 7379（12） A , β = 96. 293（1）°, V =2133.0（4）A^3. Z= 2, R1=-0.0772, wR2= 0. 2246. The building block of compound 1 consists of one （W6O19）^2-and one protonated ligand H2bbi. The 3D supramolecular network was formed through the hydrogen bonding interactions between the adjacent building blocks.
