The material described by Hf2SiH is I4/mcm-derived structured and crystallizes in the tetragonal I4/mcm space group. Hf(1) is bonded in a distorted L-shaped geometry to four equivalent Si(1) and two equivalent H(1) atoms. Si(1) is bonded in a 10-coordinate geometry to eight equivalent Hf(1) and two equivalent Si(1) atoms. H(1) is bonded to four equivalent Hf(1) atoms to form edge-sharing HHf4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
