The crystal structure described by MgVF5 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded to one F(1), two equivalent F(2), and two equivalent F(3) atoms to form distorted MgF5 trigonal bipyramids that share corners with six equivalent V(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 5-67°. V(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form VF6 octahedra that share corners with two equivalent V(1)F6 octahedra and corners with six equivalent Mg(1)F5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 46°. 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 V(1) atoms. In the second F site, F(2) is bonded in a linear geometry to one Mg(1) and one V(1) atom. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Mg(1) and one V(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
