Materials Data on Ge4Ir by Materials Project
IrGe4 crystallizes in the trigonal P3_1 space group. The structure is three-dimensional. Ir is bonded in a 8-coordinate geometry to eight Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.55–2.64 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to two equivalent Ir and three Ge atoms. There are two shorter (2.61 Å) and one longer (2.90 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ir and seven Ge atoms. There are a spread of Ge–Ge bond distances ranging from 2.77–2.87 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ir and three Ge atoms. In the fourth Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ir and three Ge atoms.
