Materials Data on Ge7Ir3 by Materials Project
Ir3Ge7 crystallizes in the cubic Im-3m space group. The structure is three-dimensional. Ir is bonded in a 8-coordinate geometry to eight Ge atoms. There are four shorter (2.58 Å) and four longer (2.61 Å) Ir–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Ir atoms. In the second Ge site, Ge is bonded to three equivalent Ir and one Ge atom to form a mixture of distorted edge and corner-sharing GeGeIr3 tetrahedra. The Ge–Ge bond length is 2.52 Å.
