Materials Data on Mn2CrO6 by Materials Project
CrMn2O6 is trigonal omega-derived structured and crystallizes in the orthorhombic Cmce space group. The structure is two-dimensional and consists of two CrMn2O6 sheets oriented in the (0, 0, 1) direction. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share edges with six equivalent MnO6 octahedra. There is two shorter (1.94 Å) and four longer (1.95 Å) Cr–O bond length. Mn+4.50+ is bonded to six O2- atoms to form MnO6 octahedra that share edges with three equivalent CrO6 octahedra and edges with three equivalent MnO6 octahedra. All Mn–O bond lengths are 1.94 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Cr3+ and two equivalent Mn+4.50+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cr3+ and two equivalent Mn+4.50+ atoms.
