Materials Data on TaMn2O3 by Materials Project
TaMn2O3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Ta is bonded in a hexagonal planar geometry to six equivalent O atoms. All Ta–O bond lengths are 2.55 Å. Mn is bonded in a 6-coordinate geometry to six equivalent O atoms. All Mn–O bond lengths are 2.13 Å. O is bonded to two equivalent Ta and four equivalent Mn atoms to form a mixture of edge, face, and corner-sharing OTa2Mn4 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
