MgSbOF3 crystallizes in the monoclinic Cm space group. Mg(1) is bonded to one O(1), one F(1), one F(2), and two equivalent F(3) atoms to form distorted corner-sharing MgOF4 trigonal bipyramids. Sb(1) is bonded in a 5-coordinate geometry to two equivalent O(1), one F(1), one F(2), and one F(3) atom. O(1) is bonded in a trigonal non-coplanar geometry to one Mg(1) and two equivalent Sb(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to one Mg(1) and one Sb(1) atom. In the second F site, F(2) is bonded in a bent 120 degrees geometry to one Mg(1) and one Sb(1) atom. In the third F site, F(3) is bonded in a distorted T-shaped geometry to two equivalent Mg(1) and one Sb(1) atom.
