The structure described by Ga2H6(SeO4)3 crystallizes in the trigonal R3c space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in an octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. In the second Ga site, Ga(2) is bonded in an octahedral geometry to three equivalent O(3) and three equivalent O(4) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(4) atom. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Ga(1) and one Se(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ga(1) and one Se(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Ga(2) and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted water-like geometry to one Ga(2), one H(1), and one H(2) atom. is represented by the CIF file [CIF]
