Materials Data on Mn(AsO3)2 by Materials Project
MnAs2O6 is beta Vanadium nitride-derived structured and crystallizes in the trigonal P-31m space group. The structure is three-dimensional. Mn2+ is bonded to six equivalent O2- atoms to form MnO6 octahedra that share corners with twelve equivalent AsO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Mn–O bond lengths are 2.25 Å. As5+ is bonded to six equivalent O2- atoms to form AsO6 octahedra that share corners with six equivalent MnO6 octahedra and edges with three equivalent AsO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All As–O bond lengths are 1.87 Å. O2- is bonded in a distorted trigonal planar geometry to one Mn2+ and two equivalent As5+ atoms.
