The crystal structure described by Mg(HSO4)2 crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded in an octahedral geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. H(1) is bonded in a single-bond geometry to one O(1) atom. S(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one H(1), one S(1), and one O(3) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Mg(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one O(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Mg(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
