The compound described by H2S is alpha U structured and crystallizes in the orthorhombic Pbcm space group. The structure is zero-dimensional and consists of eight hydrogen sulfide molecules. H(1,2,3) is bonded in a single-bond geometry to one S(1,2) atom. S(1,2) is bonded in an L-shaped geometry to two equivalent H(1,2,3) atoms. is represented by the CIF card [CIF]
