Title: Materials Data on Ni3(AsO4)2 by Materials Project

Abstract

Ni3(AsO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with three NiO6 octahedra, corners with six AsO4 tetrahedra, and edges with two NiO6 octahedra. The corner-sharing octahedra tilt angles range from 52–60°. There are a spread of Ni–O bond distances ranging from 2.00–2.16 Å. In the second Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with two NiO6 octahedra, corners with four AsO4 tetrahedra, edges with three NiO6 octahedra, and an edgeedge with one AsO4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–60°. There are a spread of Ni–O bond distances ranging from 2.05–2.24 Å. In the third Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with three NiO6 octahedra, corners with four AsO4 tetrahedra, edges with three NiO6 octahedra, and an edgeedge with one AsO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of Ni–O bond distances ranging from 2.02–2.22 Å. There are two inequivalent As5+ sites. In themore » first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with five NiO6 octahedra and edges with two NiO6 octahedra. The corner-sharing octahedra tilt angles range from 53–60°. There are a spread of As–O bond distances ranging from 1.71–1.77 Å. In the second As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with nine NiO6 octahedra. The corner-sharing octahedra tilt angles range from 50–61°. There is three shorter (1.73 Å) and one longer (1.78 Å) As–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ni2+ and one As5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni2+ and one As5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni2+ and one As5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to three Ni2+ and one As5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni2+ and one As5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ni2+ and one As5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni2+ and one As5+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ni2+ and one As5+ atom.« less
