A study is reported of the preparation, chemical composition, and crystal structure of binary compounds of Li3N with other nitrides, i.e., Mg3N2, AlN, BN, and Si3N4. Most of the crystal structures are related to an antifluorite system. Except for LiMgN, the compounds are pure lithium ion conductors. A new compound, Li8SiN4, has the highest lithium ion conductivity (viz., 1 × 10-3 S m-1 at 298 K) of the double-metal nitrides investigated.
