Materials Data on Ca(NiO2)2 by Materials Project
Abstract
Ca(NiO2)2 is Spinel structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ca2+ is bonded to four O2- atoms to form CaO4 tetrahedra that share corners with twelve NiO6 octahedra. The corner-sharing octahedra tilt angles range from 55–66°. There are three shorter (2.17 Å) and one longer (2.18 Å) Ca–O bond lengths. There are four inequivalent Ni3+ sites. In the first Ni3+ site, Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six equivalent CaO4 tetrahedra and edges with six NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.93–2.05 Å. In the second Ni3+ site, Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six equivalent CaO4 tetrahedra and edges with six NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.96–2.06 Å. In the third Ni3+ site, Ni3+ is bonded to six O2- atoms to form distorted NiO6 octahedra that share corners with six equivalent CaO4 tetrahedra and edges with six NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.93–2.15 Å. In the fourth Ni3+ site, Ni3+ is bonded to six O2-more »
