The compound described by HfH2 is Fluorite-like structured and crystallizes in the tetragonal I4/mmm space group. Hf(1) is bonded in a body-centered cubic geometry to eight equivalent H(1) atoms. H(1) is bonded to four equivalent Hf(1) atoms to form a mixture of corner and edge-sharing HHf4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
