The material structure described by In(OH)3 crystallizes in the trigonal R-3 space group. There are two inequivalent In sites. In the first In site, In(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 47-49°. In the second In site, In(2) is bonded to six equivalent O(2) atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent In(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one In(1), one In(2), and one H(2) atom. is represented by the CIF file [CIF]
