Ga(OH)3 crystallizes in the trigonal R-3 space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles range from 41-43°. In the second Ga site, Ga(2) is bonded to six equivalent O(2) atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles are 41°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ga(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Ga(1), one Ga(2), and one H(2) atom.

In the first Ga site, Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles range from 41-43°. Both Ga(1)-O(2) bond lengths are 1.98 Å. There are two shorter (1.97 Å) and two longer (2.03 Å) Ga(1)-O(1) bond lengths. In the second Ga site, Ga(2) is bonded to six equivalent O(2) atoms to form corner-sharing GaO6 octahedra. The corner-sharing octahedral tilt angles are 41°. All Ga(2)-O(2) bond lengths are 1.99 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. The H(1)-O(1) bond length is 0.99 Å.
