The structure described by Hf2Pt3 crystallizes in the tetragonal I4/mmm space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent Pt(1) and five equivalent Pt(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Hf(1) atoms. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to five equivalent Hf(1) atoms. is represented by the CIF file [CIF]
