NaSb(OF2)2 is Upper Bainite-derived structured and crystallizes in the monoclinic Cc space group. Na(1) is bonded to one O(1), one O(2), one F(1), one F(2), one F(3), and one F(4) atom to form NaO2F4 octahedra that share corners with six equivalent Sb(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 41-56°. Sb(1) is bonded to one O(1), one O(2), one F(1), one F(2), one F(3), and one F(4) atom to form SbO2F4 octahedra that share corners with six equivalent Na(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 41-56°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Na(1) and one Sb(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Na(1) and one Sb(1) atom. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 120 degrees geometry to one Na(1) and one Sb(1) atom. In the second F site, F(2) is bonded in a bent 150 degrees geometry to one Na(1) and one Sb(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to one Na(1) and one Sb(1) atom. In the fourth F site, F(4) is bonded in a distorted bent 120 degrees geometry to one Na(1) and one Sb(1) atom.
