Materials Data on Ca3(GeIr)4 by Materials Project
Ca3(IrGe)4 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Ca is bonded in a 8-coordinate geometry to four equivalent Ir and four equivalent Ge atoms. All Ca–Ir bond lengths are 3.15 Å. All Ca–Ge bond lengths are 3.14 Å. Ir is bonded in a 7-coordinate geometry to three equivalent Ca and four equivalent Ge atoms. There are one shorter (2.37 Å) and three longer (2.53 Å) Ir–Ge bond lengths. Ge is bonded in a 7-coordinate geometry to three equivalent Ca and four equivalent Ir atoms.
