Title: Materials Data on Mn2NiO3 by Materials Project

Abstract

Mn2NiO3 is Caswellsilverite-like structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with three equivalent MnO6 octahedra, corners with three equivalent NiO6 octahedra, edges with three equivalent NiO6 octahedra, and edges with nine equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 0–3°. There are three shorter (2.23 Å) and three longer (2.24 Å) Mn–O bond lengths. Ni2+ is bonded to six equivalent O2- atoms to form NiO6 octahedra that share corners with six equivalent MnO6 octahedra, edges with six equivalent MnO6 octahedra, and edges with six equivalent NiO6 octahedra. The corner-sharing octahedral tilt angles are 3°. All Ni–O bond lengths are 2.15 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Mn2+ and three equivalent Ni2+ atoms to form a mixture of edge and corner-sharing OMn3Ni3 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to six equivalent Mn2+ atoms to form a mixture of edge and corner-sharing OMn6 octahedra. The corner-sharing octahedral tilt angles are 0°.
