Materials Data on Ce2Al3Ge4 by Materials Project
Ce2Al3Ge4 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Ce is bonded in a 8-coordinate geometry to eight Ge atoms. There are a spread of Ce–Ge bond distances ranging from 3.10–3.22 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded to six Ge atoms to form distorted corner-sharing AlGe6 octahedra. The corner-sharing octahedral tilt angles are 31°. There are four shorter (2.59 Å) and two longer (2.80 Å) Al–Ge bond lengths. In the second Al site, Al is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Al–Ge bond distances ranging from 2.54–2.86 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ce and five Al atoms. In the second Ge site, Ge is bonded in a 7-coordinate geometry to four equivalent Ce and three Al atoms.
