NaMgF3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent F(2) and six equivalent F(1) atoms. Mg(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form corner-sharing MgF6 octahedra. The corner-sharing octahedral tilt angles range from 31-32°. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 5-coordinate geometry to three equivalent Na(1) and two equivalent Mg(1) atoms. In the second F site, F(2) is bonded to two equivalent Na(1) and two equivalent Mg(1) atoms to form distorted corner-sharing FNa2Mg2 tetrahedra.
NaMgF3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent F(2) and six equivalent F(1) atoms. There is one shorter (2.26 Å) and one longer (2.35 Å) Na(1)-F(2) bond length. There are a spread of Na(1)-F(1) bond distances ranging from 2.29-2.68 Å. Mg(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form corner-sharing MgF6 octahedra. The corner-sharing octahedral tilt angles range from 31-32°. Both Mg(1)-F(2) bond lengths are 1.97 Å. All Mg(1)-F(1) bond lengths are 1.98 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 5-coordinate geometry to three equivalent Na(1) and two equivalent Mg(1) atoms. In the second F site, F(2) is bonded to two equivalent Na(1) and two equivalent Mg(1) atoms to form distorted corner-sharing FNa2Mg2 tetrahedra.
