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.

Materials Data on InHSeO4 by Materials Project

InHSeO4 crystallizes in the triclinic P-1 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 a mixture of edge and corner-sharing InO6 octahedra. The corner-sharing octahedra tilt angles range from 44–49°. There are a spread of In–O bond distances ranging from 2.12–2.27 Å. In the second In3+ site, In3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing InO6 octahedra. The corner-sharing octahedra tilt angles range from 44–49°. There are a spread of In–O bond distances ranging from 2.12–2.27 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 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.80 Å. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.70–1.80 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one In3+ and one Se4+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one In3+ and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two In3+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one In3+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two In3+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent In3+ and one Se4+ atom. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to two equivalent In3+ and one Se4+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one In3+ and one Se4+ atom.
