Materials Data on Sn(PO3)3 by Materials Project

Abstract

Sn(PO3)3 crystallizes in the hexagonal P-6c2 space group. The structure is three-dimensional. Sn3+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent PO4 tetrahedra. All Sn–O bond lengths are 2.24 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent SnO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There is two shorter (1.51 Å) and two longer (1.61 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent P5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn3+ and one P5+ atom.
