The structure described by Hg is beta Sn structured and crystallizes in the tetragonal I4_1/amd space group. Hg(1) is bonded to six equivalent Hg(1) atoms to form a mixture of distorted corner and edge-sharing HgHg6 pentagonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
