Materials Data on SrCaGe by Materials Project
SrCaGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are a spread of Sr–Ge bond distances ranging from 3.30–3.62 Å. Ca is bonded to four equivalent Ge atoms to form a mixture of distorted corner and edge-sharing CaGe4 tetrahedra. There are a spread of Ca–Ge bond distances ranging from 3.07–3.12 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Sr and four equivalent Ca atoms.
