Li3SrMnN3 crystallizes in the trigonal R-3 space group. Li(1) is bonded to four equivalent N(1) atoms to form distorted LiN4 tetrahedra that share corners with four equivalent Sr(1)N6 octahedra, corners with six equivalent Li(1)N4 tetrahedra, edges with two equivalent Sr(1)N6 octahedra, and edges with three equivalent Li(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 24-54°. Sr(1) is bonded to six equivalent N(1) atoms to form SrN6 octahedra that share corners with twelve equivalent Li(1)N4 tetrahedra, edges with three equivalent Sr(1)N6 octahedra, and edges with six equivalent Li(1)N4 tetrahedra. Mn(1) is bonded in a trigonal non-coplanar geometry to three equivalent N(1) atoms. N(1) is bonded in a 7-coordinate geometry to four equivalent Li(1), two equivalent Sr(1), and one Mn(1) atom.

The corner-sharing octahedral tilt angles range from 24-54°. There are a spread of Li(1)-N(1) bond distances ranging from 2.08-2.24 Å. Sr(1) is bonded to six equivalent N(1) atoms to form SrN6 octahedra that share corners with twelve equivalent Li(1)N4 tetrahedra, edges with three equivalent Sr(1)N6 octahedra, and edges with six equivalent Li(1)N4 tetrahedra. There are three shorter (2.64 Å) and three longer (2.77 Å) Sr(1)-N(1) bond lengths. Mn(1) is bonded in a trigonal non-coplanar geometry to three equivalent N(1) atoms. All Mn(1)-N(1) bond lengths are 1.77 Å. N(1) is bonded in a 7-coordinate geometry to four equivalent Li(1), two equivalent Sr(1), and one Mn(1) atom.
