Materials Data on Li2CaGe by Materials Project
Li2CaGe is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li is bonded in a distorted body-centered cubic geometry to four equivalent Ca and four equivalent Ge atoms. All Li–Ca bond lengths are 2.87 Å. All Li–Ge bond lengths are 2.87 Å. Ca is bonded in a 8-coordinate geometry to eight equivalent Li and six equivalent Ge atoms. All Ca–Ge bond lengths are 3.32 Å. Ge is bonded in a distorted body-centered cubic geometry to eight equivalent Li and six equivalent Ca atoms.
