The structure described by HgF2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. Hg(1) is bonded to six equivalent F(1) atoms to form a mixture of corner and edge-sharing HgF6 octahedra. The corner-sharing octahedral tilt angles are 53°. F(1) is bonded in a trigonal planar geometry to three equivalent Hg(1) atoms. is represented by the CIF file [CIF]
