Materials Data on IrOs2Br by Materials Project
Os2IrBr is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Os+1.50- is bonded to four equivalent Ir4+ and four equivalent Br1- atoms to form a mixture of distorted corner, edge, and face-sharing OsIr4Br4 tetrahedra. All Os–Ir bond lengths are 2.73 Å. All Os–Br bond lengths are 2.73 Å. Ir4+ is bonded in a 8-coordinate geometry to eight equivalent Os+1.50- and six equivalent Br1- atoms. All Ir–Br bond lengths are 3.15 Å. Br1- is bonded in a distorted body-centered cubic geometry to eight equivalent Os+1.50- and six equivalent Ir4+ atoms.
