NiH12SO9 crystallizes in the trigonal R3 space group. Ni(1) is bonded in an octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. There are four 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) and one O(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(1) and one O(3) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(2) and one O(3) atom. S(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ni(1), one H(1), and one H(3) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one Ni(1), one H(2), and one H(4) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one H(2), one H(3), one H(4), and one S(1) atom.
