Materials Data on UIrPt4 by Materials Project
UPt4Ir is beta-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. U4+ is bonded in a 12-coordinate geometry to twelve equivalent Pt2- atoms. All U–Pt bond lengths are 3.09 Å. Ir4+ is bonded in a 12-coordinate geometry to twelve equivalent Pt2- atoms. All Ir–Pt bond lengths are 3.09 Å. Pt2- is bonded to three equivalent U4+, three equivalent Ir4+, and six equivalent Pt2- atoms to form a mixture of edge, corner, and face-sharing PtU3Ir3Pt6 cuboctahedra. There are three shorter (2.63 Å) and three longer (2.65 Å) Pt–Pt bond lengths.
