Abstract

An x-ray powder diffraction experiment on solid H₂S was performed with a diamond anvil cell and an image plate to determine the unknown structures of phases I' and IV up to 25 GPa at room temperature. The structures of phases I' and IV were found to be cubic T⁴ - P2₁3 and tetragonal D²⁰_4h -I4₁/acd, respectively. In phase I', the H₂S molecule had 6-fold asymmetric coordination which brought a displacement from face-center. In phase IV, the molecules were found to form spiral chains along the c axis with partial loss of molecularity. The chains were linked by hydrogen bonds.
