Materials Data on Li2ScP2HO8 by Materials Project

Li2ScP2HO8 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.99–2.48 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.99–2.40 Å. Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Sc–O bond distances ranging from 2.05–2.20 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent ScO6 octahedra. The corner-sharing octahedra tilt angles range from 26–52°. There are a spread of P–O bond distances ranging from 1.53–1.60 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent ScO6 octahedra. The corner-sharing octahedra tilt angles range from 23–53°. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.04 Å) and one longer (1.54 Å) H–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Sc3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Sc3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+, one P5+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one P5+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Sc3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Sc3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Sc3+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Sc3+, and one P5+ atom.
