Mg(ZnN)2 crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded to six equivalent N(1) atoms to form MgN6 octahedra that share corners with twelve equivalent Zn(1)N4 tetrahedra, edges with six equivalent Mg(1)N6 octahedra, and edges with six equivalent Zn(1)N4 tetrahedra. Zn(1) is bonded to four equivalent N(1) atoms to form distorted ZnN4 tetrahedra that share corners with six equivalent Mg(1)N6 octahedra, corners with six equivalent Zn(1)N4 tetrahedra, edges with three equivalent Mg(1)N6 octahedra, and edges with three equivalent Zn(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-55°. N(1) is bonded in a 7-coordinate geometry to three equivalent Mg(1) and four equivalent Zn(1) atoms.

Mg(1) is bonded to six equivalent N(1) atoms to form MgN6 octahedra that share corners with twelve equivalent Zn(1)N4 tetrahedra, edges with six equivalent Mg(1)N6 octahedra, and edges with six equivalent Zn(1)N4 tetrahedra. All Mg(1)-N(1) bond lengths are 2.33 Å. Zn(1) is bonded to four equivalent N(1) atoms to form distorted ZnN4 tetrahedra that share corners with six equivalent Mg(1)N6 octahedra, corners with six equivalent Zn(1)N4 tetrahedra, edges with three equivalent Mg(1)N6 octahedra, and edges with three equivalent Zn(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-55°. There are three shorter (2.02 Å) and one longer (2.40 Å) Zn(1)-N(1) bond length. N(1) is bonded in a 7-coordinate geometry to three equivalent Mg(1) and four equivalent Zn(1) atoms.
