Mn2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. Mn(1) is bonded to six equivalent O(1) atoms to form a mixture of corner, face, and edge-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles range from 47-60°. O(1) is bonded to four equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing OMn4 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 47-60°. There are three shorter (2.03 Å) and three longer (2.11 Å) Mn(1)-O(1) bond lengths. O(1) is bonded to four equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing OMn4 trigonal pyramids.
