BaGe2S5 crystallizes in the cubic Fd-3m space group. Ba(1) is bonded in a distorted hexagonal planar geometry to six equivalent S(2) atoms. Ge(1) is bonded to one S(2) and three equivalent S(1) atoms to form corner-sharing GeS4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to two equivalent Ge(1) atoms. In the second S site, S(2) is bonded to three equivalent Ba(1) and one Ge(1) atom to form a mixture of edge and corner-sharing SBa3Ge tetrahedra.
