The crystal structure described by NaSrFeF6 crystallizes in the orthorhombic P2_12_12_1 space group. Na(1) is bonded to one F(1), one F(2), one F(5), one F(6), and two equivalent F(3) atoms to form distorted NaF6 octahedra that share corners with two equivalent Na(1)F6 octahedra, corners with two equivalent Fe(1)F6 octahedra, and edges with two equivalent Fe(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 53-71°. Sr(1) is bonded in a 7-coordinate geometry to one F(1), one F(2), one F(3), one F(5), one F(6), and two equivalent F(4) atoms. Fe(1) is bonded to one F(1), one F(2), one F(3), one F(4), one F(5), and one F(6) atom to form FeF6 octahedra that share corners with two equivalent Na(1)F6 octahedra and edges with two equivalent Na(1)F6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are six inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Sr(1), and one Fe(1) atom. In the second F site, F(2) is bonded in a trigonal planar geometry to one Na(1), one Sr(1), and one Fe(1) atom. In the third F site, F(3) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Sr(1), and one Fe(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one Fe(1) atom. In the fifth F site, F(5) is bonded in a distorted trigonal planar geometry to one Na(1), one Sr(1), and one Fe(1) atom. In the sixth F site, F(6) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Sr(1), and one Fe(1) atom. is represented by the CIF card [CIF]
