Materials Data on Sr3Cu3(PO4)4 by Materials Project
Sr3Cu3(PO4)4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.53–3.02 Å. In the second Sr2+ site, Sr2+ is bonded to six O2- atoms to form distorted SrO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent CuO5 trigonal bipyramids. There are a spread of Sr–O bond distances ranging from 2.47–2.60 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with five PO4 tetrahedra and an edgeedge with one SrO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.98–2.25 Å. In the second Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.94 Å) and two longer (2.03 Å) Cu–O bond length. 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 two equivalent SrO6 octahedra and corners with three equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 42–59°. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SrO6 octahedra and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 55°. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Cu2+, and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+, one Cu2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, one Cu2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, two Cu2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Cu2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Sr2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to two Sr2+, one Cu2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+ and one P5+ atom.
