Materials Data on SrTi(PO4)2 by Materials Project
Abstract
SrTi(PO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sr2+ is bonded to eight O2- atoms to form distorted SrO8 hexagonal bipyramids that share corners with four equivalent PO4 tetrahedra, edges with two equivalent SrO8 hexagonal bipyramids, edges with two equivalent TiO6 octahedra, and edges with two equivalent PO4 tetrahedra. There are a spread of Sr–O bond distances ranging from 2.66–2.77 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent PO4 tetrahedra and edges with two equivalent SrO8 hexagonal bipyramids. There are a spread of Ti–O bond distances ranging from 1.90–2.01 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent SrO8 hexagonal bipyramids, corners with three equivalent TiO6 octahedra, and an edgeedge with one SrO8 hexagonal bipyramid. The corner-sharing octahedra tilt angles range from 31–49°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Sr2+, one Ti4+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+,more »
