Ga3O5 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(2), one O(4), and two equivalent O(1) atoms to form GaO4 tetrahedra that share corners with four equivalent Ga(2)O6 octahedra and corners with three equivalent Ga(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 51-62°. In the second Ga site, Ga(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form GaO6 octahedra that share corners with four equivalent Ga(1)O4 tetrahedra, corners with four equivalent Ga(3)O4 tetrahedra, and edges with two equivalent Ga(2)O6 octahedra. In the third Ga site, Ga(3) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form GaO4 tetrahedra that share corners with four equivalent Ga(2)O6 octahedra and corners with three equivalent Ga(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 55-61°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Ga(1), one Ga(2), and one Ga(3) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Ga(1) and two equivalent Ga(2) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Ga(3) and two equivalent Ga(2) atoms. In the fourth O site, O(4) is bonded in a water-like geometry to one Ga(1) and one Ga(3) atom.
