Li2Ga2GeS6 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded in a distorted see-saw-like geometry to one S(1), one S(3), and two equivalent S(2) atoms. Ga(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form GaS4 tetrahedra that share corners with two equivalent Ga(1)S4 tetrahedra and corners with two equivalent Ge(1)S4 tetrahedra. Ge(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form GeS4 tetrahedra that share corners with four equivalent Ga(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to one Li(1), one Ga(1), and one Ge(1) atom. In the second S site, S(2) is bonded to two equivalent Li(1), one Ga(1), and one Ge(1) atom to form corner-sharing SLi2GaGe tetrahedra. In the third S site, S(3) is bonded in a trigonal non-coplanar geometry to one Li(1) and two equivalent Ga(1) atoms.
Li2Ga2GeS6 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded in a distorted see-saw-like geometry to one S(1), one S(3), and two equivalent S(2) atoms.
