TaMn2O3 crystallizes in the hexagonal P6/mmm space group. Ta(1) is bonded in a hexagonal planar geometry to six equivalent O(1) atoms. Mn(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to two equivalent Ta(1) and four equivalent Mn(1) atoms to form a mixture of face, edge, and corner-sharing OTa2Mn4 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
