In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Na(1), one Na(2), and one C(1) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one Sn(1) atom. In the second F site, F(2) is bonded in a trigonal non-coplanar geometry to one Na(1), one Na(2), and one Sn(2) atom. In the third F site, F(3) is bonded to one Na(2), two equivalent Na(1), and one Sn(2) atom to form distorted edge-sharing FNa3Sn trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
