Title: Materials Data on NaMn2O4 by Materials Project

Abstract

NaMn2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Na1+ is bonded to four equivalent O2- atoms to form NaO4 tetrahedra that share corners with twelve equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 60–63°. All Na–O bond lengths are 2.18 Å. Mn+3.50+ is bonded to six equivalent O2- atoms to form MnO6 octahedra that share corners with six equivalent NaO4 tetrahedra and edges with six equivalent MnO6 octahedra. There are four shorter (1.98 Å) and two longer (2.11 Å) Mn–O bond lengths. O2- is bonded to one Na1+ and three equivalent Mn+3.50+ atoms to form a mixture of distorted edge and corner-sharing ONaMn3 tetrahedra.
