Materials Data on KMnO2 by Materials Project

Abstract

KMnO2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.67–3.07 Å. Mn3+ is bonded to five O2- atoms to form edge-sharing MnO5 square pyramids. There are a spread of Mn–O bond distances ranging from 1.95–2.29 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent K1+ and two equivalent Mn3+ atoms. In the second O2- site, O2- is bonded in a 6-coordinate geometry to three equivalent K1+ and three equivalent Mn3+ atoms.
