Materials Data on Ni4P2O9 by Materials Project
Abstract
Ni4P2O9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to five O2- atoms to form NiO5 trigonal bipyramids that share corners with four PO4 tetrahedra, a cornercorner with one NiO5 trigonal bipyramid, an edgeedge with one NiO6 octahedra, and an edgeedge with one NiO5 trigonal bipyramid. There are a spread of Ni–O bond distances ranging from 1.96–2.16 Å. In the second Ni2+ site, Ni2+ is bonded to five O2- atoms to form NiO5 trigonal bipyramids that share corners with four PO4 tetrahedra, a cornercorner with one NiO5 trigonal bipyramid, an edgeedge with one NiO6 octahedra, and an edgeedge with one NiO5 trigonal bipyramid. There are a spread of Ni–O bond distances ranging from 1.95–2.09 Å. In the third Ni2+ site, Ni2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Ni–O bond distances ranging from 1.90–1.99 Å. In the fourth Ni2+ site, Ni2+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with five PO4 tetrahedra, an edgeedge with one NiO6 octahedra, and edges with two NiO5 trigonal bipyramids.
