SrCeN2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Sr(1) is bonded to two equivalent N(1) and four equivalent N(2) atoms to form SrN6 octahedra that share corners with six equivalent Sr(1)N6 octahedra, edges with four equivalent Sr(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 Sr(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 Sr(1) and four equivalent Ce(1) atoms to form NSr2Ce4 octahedra that share corners with six equivalent N(1)Sr2Ce4 octahedra, edges with four equivalent N(1)Sr2Ce4 octahedra, and edges with eight equivalent N(2)Sr4Ce2 octahedra. The corner-sharing octahedra are not tilted. In the second N site, N(2) is bonded to four equivalent Sr(1) and two equivalent Ce(1) atoms to form NSr4Ce2 octahedra that share corners with six equivalent N(2)Sr4Ce2 octahedra, edges with four equivalent N(2)Sr4Ce2 octahedra, and edges with eight equivalent N(1)Sr2Ce4 octahedra. The corner-sharing octahedra are not tilted.
