Materials Data on NiO2 by Materials Project

Abstract

NiO2 is Rutile-like structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Ni4+ sites. In the first Ni4+ site, Ni4+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ni–O bond distances ranging from 1.86–1.89 Å. In the second Ni4+ site, Ni4+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ni–O bond distances ranging from 1.85–1.88 Å. In the third Ni4+ site, Ni4+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ni–O bond distances ranging from 1.85–1.88 Å. In the fourth Ni4+ site, Ni4+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ni–O bond distances ranging from 1.85–1.89 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ni4+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ni4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ni4+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ni4+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to three Ni4+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to three Ni4+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to three Ni4+ atoms. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three Ni4+ atoms.
