La{sub 1-x}Ca{sub x}N{sub 1-x/3} (0 < x < 0.7) has been prepared by reacting LaN with Ca{sub 3}N{sub 2} at temperatures between 1200 and 1300{degrees}C. All the phases have the LaN-like rock-salt structure with no evidence for ordering between La and Ca or of the x/3 N vacancies. The lattice parameters of materials with different compositions lie between those of the isostructural LaN and CaNH according to Vegard law. Ca adopts octahedral coordination in the title compound, in contrast to its tetrahedral coordination geometry in Ca{sub 3}N{sub 2}. The materials are poorly conducting.
