The crystal structure of hydro-thermally synthesized ( = 493 K, 7 d) caesium gallium bis-[hydrogen arsenate(V)], CsGa(HAsO), was solved by single-crystal X-ray diffraction. The compound crystallizes in the common RbAl(HAsO) structure type (32) and consists of a basic tetra-hedral-octa-hedral framework topology that houses Cs cations in its channels. The AsO tetra-hedron is disordered over two positions with site occupancy factors of 0.946 (1) and 0.054 (1). Strong hydrogen bonds strengthen the network. The structure was refined as inversion twin.
通过单晶X射线衍射解析了水热合成（ = 493 K，7 天）的铯镓双[砷酸氢（V）]，CsGa(HAsO₄)₂的晶体结构。该化合物以常见的RbAl(HAsO₄)₂结构类型（32）结晶，由一个基本的四面体 - 八面体框架拓扑结构组成，其通道中容纳Cs阳离子。AsO₄四面体在两个位置上无序，位点占有率因子分别为0.946 (1) 和0.054 (1)。强氢键加强了网络结构。该结构被精修为倒反孪晶。
