Materials Data on SrMn2O6 by Materials Project
SrMn2O6 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Sr2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Sr–O bond lengths are 2.65 Å. Mn5+ is bonded to six equivalent O2- atoms to form distorted edge-sharing MnO6 pentagonal pyramids. All Mn–O bond lengths are 1.90 Å. O2- is bonded in a 3-coordinate geometry to one Sr2+ and two equivalent Mn5+ atoms.
