Title: Materials Data on NaMn2O4 by Materials Project

Abstract

NaMn2O4 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.40–2.68 Å. There are two inequivalent Mn+3.50+ sites. In the first Mn+3.50+ site, Mn+3.50+ is bonded to six O2- atoms to form edge-sharing MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.91–2.01 Å. In the second Mn+3.50+ site, Mn+3.50+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 1.96–2.62 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+ and two equivalent Mn+3.50+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and three Mn+3.50+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one Na1+ and four Mn+3.50+ atoms. In the fourth O2- site, O2- is bonded to two equivalent Na1+ and three Mn+3.50+ atoms to form distorted edge-sharing ONa2Mn3 square pyramids.
