Inorganic nitrides with wurtzite crystal structures are well-known semiconductors used in optical and electronic devices. In contrast, rocksalt-structured known for their superconducting refractory properties. Breaking this dichotomy, here we report ternary nitride rocksalt structures, remarkable properties, the general chemical formula Mg
