Title: Materials Data on Ca4P6O19 by Materials Project

Abstract

Ca4P6O19 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.39–2.95 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent CaO7 pentagonal bipyramids. There are a spread of Ca–O bond distances ranging from 2.23–2.51 Å. In the third Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.26–2.80 Å. In the fourth Ca2+ site, Ca2+ is bonded to seven O2- atoms to form distorted CaO7 pentagonal bipyramids that share corners with seven PO4 tetrahedra, edges with two equivalent CaO6 octahedra, and an edgeedge with one CaO7 pentagonal bipyramid.
