Materials Data on Si2Ir by Materials Project
IrSi2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ir is bonded in a body-centered cubic geometry to eight equivalent Si atoms. All Ir–Si bond lengths are 2.48 Å. Si is bonded to four equivalent Ir atoms to form a mixture of edge and corner-sharing SiIr4 tetrahedra.
