In2O3 is Corundum-like structured and crystallizes in the orthorhombic Pbcn space group. In(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted face, corner, and edge-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 51-72°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing OIn4 tetrahedra. In the second O site, O(2) is bonded to four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing OIn4 trigonal pyramids.

In(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted face, corner, and edge-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 51-72°. There is one shorter (2.14 Å) and one longer (2.23 Å) In(1)-O(2) bond length. There are a spread of In(1)-O(1) bond distances ranging from 2.16-2.30 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing OIn4 tetrahedra. In the second O site, O(2) is bonded to four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing OIn4 trigonal pyramids.
