ScO2 is Marcasite structured and crystallizes in the orthorhombic Pnnm space group. Sc(1) is bonded to six equivalent O(1) atoms to form a mixture of edge and corner-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles are 58°. O(1) is bonded in a trigonal planar geometry to three equivalent Sc(1) atoms.

The corner-sharing octahedral tilt angles are 58°. There are two shorter (2.11 Å) and four longer (2.13 Å) Sc(1)-O(1) bond lengths. O(1) is bonded in a trigonal planar geometry to three equivalent Sc(1) atoms.
