The material structure described by MgH8(O6Cl)2 is alpha structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two MgH8(O6Cl)2 clusters. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form MgO6 octahedra that share corners with two equivalent Cl(1)O4 tetrahedra. 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 single-bond geometry to one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent H(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mg(1) and one Cl(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cl(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent H(2) atoms. In the fifth O site, O(5) is bonded in a single-bond geometry to one Cl(1) atom. Cl(1) is bonded to one O(2), one O(5), and two equivalent O(3) atoms to form ClO4 tetrahedra that share  a cornercorner with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 48°. is represented by the CIF card [CIF]
