Abstract

Samples of ternary nitride fluorides, Mg ₃NF ₃ and Mg ₂NF have been prepared by solid state reaction of Mg ₃N ₂ and MgF ₂ at 13231423 K and investigated by powder X-ray and powder neutron diffraction techniques. Mg ₃NF ₃ is cubic (space group: Pm3m) and has a structure related to rock-salt MgO, but with one cation site vacant. Mg ₂NF is tetragonal (space group: I4 ₁/amd) and has an anti-LiFeO ₂ related structure. Both compounds are essentially ionic and form structures in which nitride and fluoride anions are crystallographically ordered. The nitride fluorides show temperature independent paramagnetic behaviour between 5 and 300 K.
