The crystal structure of hydrothermally synthesized (T = 493 K, 7 d) caesium gallium bis[hydrogen arsenate(V)], CsGa(HAsO4)2, was solved by single-crystal X-ray diffraction. The compound crystallizes in the common RbAl(HAsO4)2 structure type (R32) and consists of a basic tetrahedral-octahedral framework topology that houses Cs+ cations in its channels. The AsO4 tetrahedron 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.
