Abstract

CaP2H6O7 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ca2+ is bonded to seven O2- atoms to form CaO7 pentagonal bipyramids that share corners with four PHO3 tetrahedra, an edgeedge with one CaO7 pentagonal bipyramid, and an edgeedge with one PHO3 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.38–2.54 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one H+0.33+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent CaO7 pentagonal bipyramids. The P–H bond length is 1.41 Å. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. In the second P5+ site, P5+ is bonded to one H+0.33+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent CaO7 pentagonal bipyramids and an edgeedge with one CaO7 pentagonal bipyramid. The P–H bond length is 1.41 Å. There are a spread of P–O bond distances ranging from 1.52–1.59 Å. There are six inequivalent H+0.33+ sites. In the first H+0.33+ site, H+0.33+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H+0.33+more »« less
