The structure described by SrCeN2 is Caswellsilverite-like structured and crystallizes in the monoclinic C2 space group. Sr(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form SrN6 octahedra that share corners with two equivalent Ce(1)N6 octahedra, corners with four 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 octahedral tilt angles range from 2-14°. Ce(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form CeN6 octahedra that share corners with two equivalent Sr(1)N6 octahedra, corners with four 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 octahedral tilt angles range from 2-14°. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Sr(1) and three equivalent Ce(1) atoms to form a mixture of distorted corner and edge-sharing NSr3Ce3 octahedra. The corner-sharing octahedral tilt angles range from 1-14°. In the second N site, N(2) is bonded to three equivalent Sr(1) and three equivalent Ce(1) atoms to form a mixture of distorted corner and edge-sharing NSr3Ce3 octahedra. The corner-sharing octahedral tilt angles range from 1-14°. is represented by the Crystallographic Information File (CIF) [CIF]
