InOOH crystallizes in the cubic P2_13 space group. In(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles are 62°. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent In(1) and one H(1) atom. In the second O site, O(2) is bonded to three equivalent In(1) and one H(1) atom to form distorted corner-sharing OIn3H trigonal pyramids.
