Materials Data on Ge3Ir by Materials Project
IrGe3 is alpha bismuth trifluoride 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 fourteen Ge atoms. There are eight shorter (2.78 Å) and six longer (3.21 Å) Ir–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a body-centered cubic geometry to four equivalent Ir and four equivalent Ge atoms. All Ge–Ge bond lengths are 2.78 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to six equivalent Ir and eight equivalent Ge atoms.
