MgWOCl4 crystallizes in the monoclinic C2 space group. Mg(1) is bonded to two equivalent Cl(1) and two equivalent Cl(2) atoms to form distorted MgCl4 tetrahedra that share corners with four equivalent W(1)Cl4O2 octahedra. The corner-sharing octahedral tilt angles are 46°. W(1) is bonded to two equivalent O(1), two equivalent Cl(1), and two equivalent Cl(2) atoms to form WCl4O2 octahedra that share corners with two equivalent W(1)Cl4O2 octahedra and corners with four equivalent Mg(1)Cl4 tetrahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a linear geometry to two equivalent W(1) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one W(1) atom. In the second Cl site, Cl(2) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one W(1) atom.
