H4OTa2O6 is Upper Bainite-derived structured and crystallizes in the cubic Fd-3m space group. The structure consists of eight H4O clusters inside a TaO3 framework. In each H4O cluster, H(1) is bonded in a single-bond geometry to one O(2) atom. O(2) is bonded in a tetrahedral geometry to four equivalent H(1) atoms. 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 44°. O(1) is bonded in a bent 150 degrees geometry to two equivalent Ta(1) atoms.

In each H4O cluster, H(1) is bonded in a single-bond geometry to one O(2) atom. The H(1)-O(2) bond length is 1.05 Å. O(2) is bonded in a tetrahedral geometry to four equivalent H(1) atoms. 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 44°. All Ta(1)-O(1) bond lengths are 1.99 Å. O(1) is bonded in a bent 150 degrees geometry to two equivalent Ta(1) atoms.
