Materials Data on In(HO)3 by Materials Project

Abstract

In(OH)3 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to six O2- atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedra tilt angles range from 47–48°. There are two shorter (2.19 Å) and four longer (2.21 Å) In–O bond lengths. In the second In3+ site, In3+ is bonded to six equivalent O2- atoms to form corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles are 48°. All In–O bond lengths are 2.21 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two In3+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent In3+ and one H1+ atom.
