The material described by Ta3Pt is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded to four equivalent Ta(2) and four equivalent Pt(1) atoms to form a mixture of distorted edge, corner, and face-sharing TaTa4Pt4 tetrahedra. In the second Ta site, Ta(2) is bonded in a 14-coordinate geometry to eight equivalent Ta(1) and six equivalent Pt(1) atoms. Pt(1) is bonded in a distorted body-centered cubic geometry to six equivalent Ta(2) and eight equivalent Ta(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
