The compound described by GeS2 crystallizes in the tetragonal I4_1/acd space group. The structure consists of a GeS2 framework. Ge(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form corner-sharing GeS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(2) is bonded in a water-like geometry to two equivalent Ge(1) atoms. In the second S site, S(1) is bonded in a water-like geometry to two equivalent Ge(1) atoms. In the third S site, S(3) is bonded in a water-like geometry to two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
