Li2SnN2 crystallizes in the trigonal P-3m1 space group. Li(1) is bonded to four equivalent N(1) atoms to form distorted LiN4 tetrahedra that share corners with six equivalent Sn(1)N6 octahedra, corners with six equivalent Li(1)N4 tetrahedra, edges with three equivalent Sn(1)N6 octahedra, and edges with three equivalent Li(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 9-57°. Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share corners with twelve equivalent Li(1)N4 tetrahedra, edges with six equivalent Sn(1)N6 octahedra, and edges with six equivalent Li(1)N4 tetrahedra. N(1) is bonded to four equivalent Li(1) and three equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing NLi4Sn3 pentagonal bipyramids.

The corner-sharing octahedral tilt angles range from 9-57°. There are three shorter (2.06 Å) and one longer (2.14 Å) Li(1)-N(1) bond length. Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share corners with twelve equivalent Li(1)N4 tetrahedra, edges with six equivalent Sn(1)N6 octahedra, and edges with six equivalent Li(1)N4 tetrahedra. All Sn(1)-N(1) bond lengths are 2.25 Å. N(1) is bonded to four equivalent Li(1) and three equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing NLi4Sn3 pentagonal bipyramids.
