Materials Data on InHSeO4 by Materials Project
InHSeO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is two-dimensional and consists of two InHSeO4 sheets oriented in the (0, 0, 1) direction. In3+ is bonded to six O2- atoms to form distorted edge-sharing InO6 octahedra. There are a spread of In–O bond distances ranging from 2.06–2.55 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.68–1.88 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent In3+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one In3+, one H1+, and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one Se4+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to two equivalent In3+ atoms.
