Pt3Sb is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted body-centered cubic geometry to four equivalent Pt(2) and four equivalent Sb(1) atoms. In the second Pt site, Pt(2) is bonded in a 14-coordinate geometry to eight equivalent Pt(1) and six equivalent Sb(1) atoms. Sb(1) is bonded in a distorted body-centered cubic geometry to six equivalent Pt(2) and eight equivalent Pt(1) atoms.
