Materials Data on LiGeIr2 by Materials Project

LiIr2Ge is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li is bonded in a body-centered cubic geometry to eight equivalent Ir and six equivalent Ge atoms. All Li–Ir bond lengths are 2.57 Å. All Li–Ge bond lengths are 2.97 Å. Ir is bonded in a distorted body-centered cubic geometry to four equivalent Li and four equivalent Ge atoms. All Ir–Ge bond lengths are 2.57 Å. Ge is bonded in a 8-coordinate geometry to six equivalent Li and eight equivalent Ir atoms.

Materials Data on LiGe2Ir by Materials Project

LiIrGe2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two LiIrGe2 ribbons oriented in the (1, 0, 0) direction. Li is bonded in a linear geometry to two equivalent Ge atoms. Both Li–Ge bond lengths are 2.60 Å. Ir is bonded in a linear geometry to two equivalent Ge atoms. Both Ir–Ge bond lengths are 2.31 Å. Ge is bonded in a linear geometry to one Li and one Ir atom.
