SrCeN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded to six equivalent N(1) atoms to form SrN6 octahedra that share corners with six equivalent Ce(1)N6 octahedra, edges with six equivalent Sr(1)N6 octahedra, and edges with six equivalent Ce(1)N6 octahedra. The corner-sharing octahedral tilt angles are 9°. Ce(1) is bonded to six equivalent N(1) atoms to form CeN6 octahedra that share corners with six equivalent Sr(1)N6 octahedra, edges with six equivalent Sr(1)N6 octahedra, and edges with six equivalent Ce(1)N6 octahedra. The corner-sharing octahedral tilt angles are 9°. N(1) is bonded to three equivalent Sr(1) and three equivalent Ce(1) atoms to form a mixture of corner and edge-sharing NSr3Ce3 octahedra. The corner-sharing octahedra are not tilted.
