Rh2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. Rh(1) is bonded to six equivalent O(1) atoms to form a mixture of corner, edge, and face-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 47-61°. O(1) is bonded to four equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing ORh4 trigonal pyramids.

The corner-sharing octahedral tilt angles range from 47-61°. There are three shorter (2.04 Å) and three longer (2.07 Å) Rh(1)-O(1) bond lengths. O(1) is bonded to four equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing ORh4 trigonal pyramids.
