Materials Data on Ir3F by Materials Project
Ir3F is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Ir sites. In the first Ir site, Ir is bonded to four equivalent Ir and four equivalent F atoms to form a mixture of distorted face, edge, and corner-sharing IrIr4F4 tetrahedra. All Ir–Ir bond lengths are 2.62 Å. All Ir–F bond lengths are 2.62 Å. In the second Ir site, Ir is bonded in a body-centered cubic geometry to eight equivalent Ir atoms. F is bonded in a body-centered cubic geometry to eight equivalent Ir atoms.
