Materials Data on CaMgGe by Materials Project
CaMgGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ca is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are a spread of Ca–Ge bond distances ranging from 3.11–3.23 Å. Mg is bonded to four equivalent Ge atoms to form a mixture of distorted edge and corner-sharing MgGe4 tetrahedra. There are two shorter (2.77 Å) and two longer (2.86 Å) Mg–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to five equivalent Ca and four equivalent Mg atoms.
