The structure described by MgSb2(O2F)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), one F(1), and one F(2) atom to form distorted MgO4F2 octahedra that share edges with three equivalent Sb(2)O4F2 octahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. In the second Sb site, Sb(2) is bonded to one O(1), one O(2), one O(3), one O(4), one F(1), and one F(2) atom to form SbO4F2 octahedra that share edges with three equivalent Mg(1)O4F2 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one Sb(1), and one Sb(2) atom. In the second O site, O(2) is bonded in a T-shaped geometry to one Mg(1), one Sb(1), and one Sb(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mg(1), one Sb(1), and one Sb(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Mg(1), one Sb(1), and one Sb(2) atom. There are two inequivalent F sites. In the first F site, F(1) is bonded in a water-like geometry to one Mg(1) and one Sb(2) atom. In the second F site, F(2) is bonded in a water-like geometry to one Mg(1) and one Sb(2) atom. is represented by the CIF file [CIF]
