NaMnO3F4 crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a distorted pentagonal planar geometry to one F(3), two equivalent F(1), and two equivalent F(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. In the second Mn site, Mn(2) is bonded in a distorted octahedral geometry to two equivalent O(2), two equivalent F(3), and two equivalent F(4) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Mn(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mn(2) and one O(3) atom. In the third O site, O(3) is bonded in a single-bond geometry to one O(2) atom. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted T-shaped geometry to two equivalent Na(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted T-shaped geometry to two equivalent Na(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a bent 120 degrees geometry to one Na(1) and one Mn(2) atom. In the fourth F site, F(4) is bonded in a single-bond geometry to one Mn(2) atom.
