Materials Data on Mg2NF by Materials Project
Mg2NF crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Mg2+ is bonded to three equivalent N3- and two equivalent F1- atoms to form a mixture of distorted corner and edge-sharing MgN3F2 square pyramids. There are two shorter (2.15 Å) and one longer (2.16 Å) Mg–N bond lengths. Both Mg–F bond lengths are 2.15 Å. N3- is bonded to six equivalent Mg2+ atoms to form a mixture of corner and edge-sharing NMg6 octahedra. The corner-sharing octahedral tilt angles are 21°. F1- is bonded in a square co-planar geometry to four equivalent Mg2+ atoms.
