The structure described by MgW2Fe2(O4Cl)2 crystallizes in the tetragonal P-4m2 space group. Mg(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to four equivalent O(1) atoms to form distorted WO4 tetrahedra that share corners with four equivalent Fe(1)ClO4 trigonal bipyramids. In the second W site, W(2) is bonded to four equivalent O(2) atoms to form WO4 tetrahedra that share corners with four equivalent Fe(1)ClO4 trigonal bipyramids. Fe(1) is bonded to two equivalent O(1), two equivalent O(2), and one Cl(1) atom to form distorted FeClO4 trigonal bipyramids that share corners with two equivalent W(1)O4 tetrahedra and corners with two equivalent W(2)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one W(1), and one Fe(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(2) and one Fe(1) atom. Cl(1) is bonded in a single-bond geometry to one Fe(1) atom. is represented by the CIF file [CIF]
