The material structure described by MgAu2(SO4)4 crystallizes in the orthorhombic Fdd2 space group. Mg(1) is bonded to two equivalent O(5), two equivalent O(6), and two equivalent O(8) atoms to form MgO6 octahedra that share corners with two equivalent S(2)O4 tetrahedra and corners with four equivalent S(1)O4 tetrahedra. Au(1) is bonded in a square co-planar geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(1), one O(3), one O(5), and one O(6) atom to form SO4 tetrahedra that share corners with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-15°. In the second S site, S(2) is bonded to one O(2), one O(4), one O(7), and one O(8) atom to form SO4 tetrahedra that share  a cornercorner with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 30°. There are eight inequivalent O sites. In the first O site, O(3) is bonded in a bent 120 degrees geometry to one Au(1) and one S(1) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one Au(1) and one S(2) atom. In the third O site, O(5) is bonded in a linear geometry to one Mg(1) and one S(1) atom. In the fourth O site, O(6) is bonded in a linear geometry to one Mg(1) and one S(1) atom. In the fifth O site, O(2) is bonded in a bent 120 degrees geometry to one Au(1) and one S(2) atom. In the sixth O site, O(7) is bonded in a single-bond geometry to one S(2) atom. In the seventh O site, O(8) is bonded in a bent 150 degrees geometry to one Mg(1) and one S(2) atom. In the eighth O site, O(1) is bonded in a bent 120 degrees geometry to one Au(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
