Ga2O3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. In the second Ga site, Ga(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted square co-planar geometry to two equivalent Ga(1) and two equivalent Ga(2) atoms. In the second O site, O(2) is bonded to two equivalent Ga(1) and two equivalent Ga(2) atoms to form corner-sharing OGa4 tetrahedra.
Ga2O3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Ga(1)-O(2) bond lengths are 1.96 Å. All Ga(1)-O(1) bond lengths are 2.17 Å. In the second Ga site, Ga(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles are 58°. Both Ga(2)-O(2) bond lengths are 2.08 Å. All Ga(2)-O(1) bond lengths are 1.98 Å. There are two inequivalent O sites.
