Title: Materials Data on Ni7(PO4)6 by Materials Project

Abstract

Ni7(PO4)6 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Ni+2.57+ sites. In the first Ni+2.57+ site, Ni+2.57+ is bonded to six O2- atoms to form NiO6 octahedra that share a cornercorner with one NiO6 octahedra, corners with four PO4 tetrahedra, an edgeedge with one NiO6 octahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Ni–O bond distances ranging from 2.01–2.20 Å. In the second Ni+2.57+ site, Ni+2.57+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four NiO6 octahedra and corners with six PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 56–57°. There are a spread of Ni–O bond distances ranging from 1.95–2.03 Å. In the third Ni+2.57+ site, Ni+2.57+ is bonded to six O2- atoms to form NiO6 octahedra that share a cornercorner with one NiO6 octahedra, corners with four PO4 tetrahedra, an edgeedge with one NiO6 octahedra, and an edgeedge with one PO4 tetrahedra.

In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ni+2.57+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni+2.57+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two Ni+2.57+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Ni+2.57+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ni+2.57+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to three Ni+2.57+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ni+2.57+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni+2.57+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ni+2.57+ and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni+2.57+ and one P5+ atom. In the fourteenth O2- site, O2- is bonded in a single-bond geometry to one P5+ atom.« less
