CaReN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ca(1) is bonded to six equivalent N(1) atoms to form CaN6 octahedra that share corners with six equivalent Re(1)N6 octahedra, edges with six equivalent Ca(1)N6 octahedra, and edges with six equivalent Re(1)N6 octahedra. The corner-sharing octahedral tilt angles are 9°. Re(1) is bonded to six equivalent N(1) atoms to form ReN6 octahedra that share corners with six equivalent Ca(1)N6 octahedra, edges with six equivalent Ca(1)N6 octahedra, and edges with six equivalent Re(1)N6 octahedra. The corner-sharing octahedral tilt angles are 9°. N(1) is bonded to three equivalent Ca(1) and three equivalent Re(1) atoms to form a mixture of corner and edge-sharing NCa3Re3 octahedra. The corner-sharing octahedra are not tilted.
