Ga2(SO4)3 crystallizes in the trigonal R-3c space group. Ga(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form GaO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra. S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with four equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-31°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to one Ga(1) and one S(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Ga(1) and one S(1) atom.

Ga(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form GaO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra. All Ga(1)-O(1) bond lengths are 1.97 Å. All Ga(1)-O(2) bond lengths are 1.96 Å. S(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with four equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-31°. Both S(1)-O(1) bond lengths are 1.48 Å. Both S(1)-O(2) bond lengths are 1.47 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to one Ga(1) and one S(1) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Ga(1) and one S(1) atom.
