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.
