首次以有机胺为结构导向剂，在水热条件下合成了微孔砷酸铟材料InAsO4-1，并对其进行了结构及性质表征。X射线单晶结构解析表明InAsO4-1分子式为InAsO4(H2O)2。晶体学数据为：Pbca,a=0.9090(4)nm,b=1.0344(4)nm,c=1.0468(4)nm,α=β=Υ=90°,V=0.9843(7)nm^3,Z=8,R=0.0480,Rw=0.1045。InAsO4-1具有三维结构，其a,b方向分别有4元环及6元环的一维孔道，结构中还含有一8^16^44^2笼，热重分析显示其结构水较稳定。

A new three-dimensional microporous indium arsenate has been synthesized for the first time from the hydrothermal reaction of H2O, InCl3.4H2O, H3AsO4 and C6H12N2.6H2O. Single crystal X-ray diffraction studies show that it has an orthorhombic (symmetry space group Pbca), with a=0.9090(4) nm, b=1.0344(4) nm, c=1.0468(4) nm. It's asymmetry unit is InAsO4(H2O)2, which produces a 4-ring and 6-ring 1D channel along the a and b axis, respectively. It also contains a cage-like structrue surrounded by 4, 6, 8-rings. The organic amine is not occluded in the structure. This structure is the first indium arsenate analog of InPO4-1.
