Materials Data on Ni(RhO2)2 by Materials Project

Ni(RhO2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Rh3+ is bonded to six equivalent O2- atoms to form RhO6 octahedra that share corners with six equivalent NiO4 tetrahedra and edges with six equivalent RhO6 octahedra. All Rh–O bond lengths are 2.07 Å. Ni2+ is bonded to four equivalent O2- atoms to form NiO4 tetrahedra that share corners with twelve equivalent RhO6 octahedra. The corner-sharing octahedra tilt angles range from 57–61°. All Ni–O bond lengths are 2.02 Å. O2- is bonded in a rectangular see-saw-like geometry to three equivalent Rh3+ and one Ni2+ atom.

Materials Data on Ni(RhO2)2 by Materials Project

Ni(RhO2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Rh3+ is bonded to six equivalent O2- atoms to form RhO6 octahedra that share corners with six equivalent NiO4 tetrahedra and edges with six equivalent RhO6 octahedra. There are two shorter (2.07 Å) and four longer (2.08 Å) Rh–O bond lengths. Ni2+ is bonded to four equivalent O2- atoms to form NiO4 tetrahedra that share corners with twelve equivalent RhO6 octahedra. The corner-sharing octahedra tilt angles range from 52–61°. All Ni–O bond lengths are 2.01 Å. O2- is bonded in a rectangular see-saw-like geometry to three equivalent Rh3+ and one Ni2+ atom.
