摘　　要：在水热的条件下合成了硼酸锌Zn[B3O4(OH)3],用组装合成的思想来描述该化合物的结构。该化合物系三硼氧聚阴离子B3O5(OH)3通过共享环外氧原子形成一维无限链,三硼氧聚阴离子链通过与ZnO4或氢键作用连接起来的网状结构。使用红外光谱、热重分析及X射线单晶衍射分析手段对该化合物结构进行了表征。该化合物属单斜晶系,P21/n空间群,晶胞参数a=6.8482(4),b=9.7967(6),c=7.7014(4),β=107.0290(10),V=494.03(5)3,Z=4。The paper synthesized zinc borate Zn[B3O4（OH）3] under hydrothermal conditions,and discussion the structure of the compound based on ＂Scale Chemistry＂.In Zn[B3O4（OH）3],triborate B3O5（OH）3 moieties link into infinite chains by sharing an exocyclic oxygen,the polytriborate chains are cross-linked by coordination with zinc and further integrated by hydrogen bonding.The compound has been characterized by infrared spectroscopy and thermogravimetric analysis as well as single crystal X-ray diffraction studies.The compound crystallizes in the monoclinic system with space group P21/n,a=6.8482（4）A°,b=9.7967（6）A°,c=7.7014（4）A°,β=107.0290（10）°,V=494.03（5）A°3,Z=4.
