The structure described by MgSO9 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 6-coordinate geometry to one O(2), one O(5), one O(7), one O(9), and two equivalent O(4) atoms. S(1) is bonded in a distorted trigonal non-coplanar geometry to one O(3), one O(5), and one O(8) atom. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one O(9) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Mg(1) and one O(3) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one S(1) and one O(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Mg(1) and one O(6) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Mg(1) and one S(1) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one O(4) atom. In the seventh O site, O(7) is bonded in a distorted single-bond geometry to one Mg(1) and one O(8) atom. In the eighth O site, O(8) is bonded in a distorted water-like geometry to one S(1) and one O(7) atom. In the ninth O site, O(9) is bonded in a bent 150 degrees geometry to one Mg(1) and one O(1) atom. is represented by the CIF file [CIF]
