The crystal structure described by MgMnN2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Mg(1) is bonded to six equivalent N(1) atoms to form MgN6 octahedra that share corners with six equivalent Mn(1)N6 octahedra, edges with six equivalent Mg(1)N6 octahedra, and edges with six equivalent Mn(1)N6 octahedra. The corner-sharing octahedral tilt angles are 6°. Mn(1) is bonded to six equivalent N(1) atoms to form MnN6 octahedra that share corners with six equivalent Mg(1)N6 octahedra, edges with six equivalent Mg(1)N6 octahedra, and edges with six equivalent Mn(1)N6 octahedra. The corner-sharing octahedral tilt angles are 6°. N(1) is bonded to three equivalent Mg(1) and three equivalent Mn(1) atoms to form a mixture of edge and corner-sharing NMg3Mn3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
