The material structure described by (TaO3)4O2 crystallizes in the cubic Fd-3m space group. The structure consists of eight water atoms inside a TaO3 framework. In the TaO3 framework, Ta(1) is bonded to six equivalent O(1) atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles are 37°. O(1) is bonded in a bent 150 degrees geometry to two equivalent Ta(1) atoms. is represented by the CIF card [CIF]
