The crystal structure described by HgCd2 crystallizes in the tetragonal I4/mmm space group. Hg(1) is bonded in a distorted q6 geometry to ten equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to five equivalent Hg(1) and five equivalent Cd(1) atoms. is represented by the CIF file [CIF]
