The material structure described by MgWF5 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded in a 7-coordinate geometry to one F(1), two equivalent F(2), and four equivalent F(3) atoms. W(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form corner-sharing WF6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are three inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent W(1) atoms. In the second F site, F(2) is bonded in a linear geometry to one Mg(1) and one W(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to two equivalent Mg(1) and one W(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
