CaCeN2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Ca(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form CaN6 octahedra that share corners with six equivalent Ca(1)N6 octahedra, edges with four equivalent Ca(1)N6 octahedra, and edges with eight equivalent Ce(1)N6 octahedra. The corner-sharing octahedra are not tilted. Ce(1) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form CeN6 octahedra that share corners with six equivalent Ce(1)N6 octahedra, edges with four equivalent Ce(1)N6 octahedra, and edges with eight equivalent Ca(1)N6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Ca(1) and four equivalent Ce(1) atoms to form NCa2Ce4 octahedra that share corners with six equivalent N(1)Ca2Ce4 octahedra, edges with four equivalent N(1)Ca2Ce4 octahedra, and edges with eight equivalent N(2)Ca4Ce2 octahedra. The corner-sharing octahedra are not tilted. In the second N site, N(2) is bonded to four equivalent Ca(1) and two equivalent Ce(1) atoms to form NCa4Ce2 octahedra that share corners with six equivalent N(2)Ca4Ce2 octahedra, edges with four equivalent N(2)Ca4Ce2 octahedra, and edges with eight equivalent N(1)Ca2Ce4 octahedra. The corner-sharing octahedra are not tilted.
