The crystal structure described by Li4Sr3Ge2N6 crystallizes in the monoclinic C2/m space group. Li(1) is bonded to one N(2) and three equivalent N(1) atoms to form distorted LiN4 tetrahedra that share corners with two equivalent Sr(2)N6 octahedra, corners with three equivalent Li(1)N4 tetrahedra, corners with three equivalent Ge(1)N4 tetrahedra,  an edgeedge with one Sr(2)N6 octahedra,  an edgeedge with one Ge(1)N4 tetrahedra, and edges with two equivalent Li(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 53-89°. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded to two equivalent N(2) and four equivalent N(1) atoms to form distorted SrN6 octahedra that share corners with four equivalent Ge(1)N4 tetrahedra, corners with eight equivalent Li(1)N4 tetrahedra, edges with two equivalent Ge(1)N4 tetrahedra, and edges with four equivalent Li(1)N4 tetrahedra. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with two equivalent Sr(2)N6 octahedra, corners with six equivalent Li(1)N4 tetrahedra,  an edgeedge with one Sr(2)N6 octahedra,  an edgeedge with one Ge(1)N4 tetrahedra, and edges with two equivalent Li(1)N4 tetrahedra. The corner-sharing octahedral tilt angles range from 24-61°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 7-coordinate geometry to three equivalent Li(1), one Sr(2), two equivalent Sr(1), and one Ge(1) atom. In the second N site, N(2) is bonded in a 7-coordinate geometry to two equivalent Li(1), one Sr(2), two equivalent Sr(1), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
