Materials Data on UPt4Au by Materials Project
UPt4Au is Cubic Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. U6+ is bonded in a 12-coordinate geometry to twelve equivalent Pt2- atoms. All U–Pt bond lengths are 3.13 Å. Pt2- is bonded to three equivalent U6+, six equivalent Pt2-, and three equivalent Au2+ atoms to form a mixture of corner, edge, and face-sharing PtU3Pt6Au3 cuboctahedra. There are three shorter (2.66 Å) and three longer (2.68 Å) Pt–Pt bond lengths. All Pt–Au bond lengths are 3.13 Å. Au2+ is bonded in a 12-coordinate geometry to twelve equivalent Pt2- atoms.
