The crystal structure described by Na2GeS3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to one S(2), one S(3), and three equivalent S(1) atoms to form distorted NaS5 trigonal bipyramids that share corners with six equivalent Na(2)S6 octahedra, corners with two equivalent Ge(1)S4 tetrahedra, corners with two equivalent Na(1)S5 trigonal bipyramids, edges with two equivalent Na(2)S6 octahedra, edges with two equivalent Ge(1)S4 tetrahedra, and edges with two equivalent Na(1)S5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 4-84°. In the second Na site, Na(2) is bonded to one S(3), two equivalent S(1), and three equivalent S(2) atoms to form distorted NaS6 octahedra that share corners with two equivalent Na(2)S6 octahedra, corners with three equivalent Ge(1)S4 tetrahedra, corners with six equivalent Na(1)S5 trigonal bipyramids, edges with three equivalent Na(2)S6 octahedra, edges with two equivalent Ge(1)S4 tetrahedra, and edges with two equivalent Na(1)S5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 24°. Ge(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form GeS4 tetrahedra that share corners with three equivalent Na(2)S6 octahedra, corners with two equivalent Ge(1)S4 tetrahedra, corners with two equivalent Na(1)S5 trigonal bipyramids, edges with two equivalent Na(2)S6 octahedra, and edges with two equivalent Na(1)S5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 26-66°. There are three inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Na(2), three equivalent Na(1), and one Ge(1) atom to form distorted SNa5Ge octahedra that share corners with two equivalent S(1)Na5Ge octahedra, corners with four equivalent S(2)Na4Ge trigonal bipyramids, edges with three equivalent S(1)Na5Ge octahedra, and edges with three equivalent S(2)Na4Ge trigonal bipyramids. The corner-sharing octahedral tilt angles are 21°.

The corner-sharing octahedral tilt angles range from 6-82°. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to one Na(1), one Na(2), and two equivalent Ge(1) atoms. is represented by the CIF file [CIF]
