Sc2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. Sc(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge, corner, and face-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. O(1) is bonded to four equivalent Sc(1) atoms to form a mixture of distorted edge and corner-sharing OSc4 trigonal pyramids.

Sc(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge, corner, and face-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. There are three shorter (2.07 Å) and three longer (2.20 Å) Sc(1)-O(1) bond lengths. O(1) is bonded to four equivalent Sc(1) atoms to form a mixture of distorted edge and corner-sharing OSc4 trigonal pyramids.
