Materials Data on Ce3(AgGe)4 by Materials Project
Abstract
Ce3Ag4Ge4 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 12-coordinate geometry to six equivalent Ag and six Ge atoms. There are four shorter (3.20 Å) and two longer (3.34 Å) Ce–Ag bond lengths. There are two shorter (3.19 Å) and four longer (3.20 Å) Ce–Ge bond lengths. In the second Ce site, Ce is bonded to eight equivalent Ag and six Ge atoms to form distorted face-sharing CeAg8Ge6 octahedra. All Ce–Ag bond lengths are 3.60 Å. There are four shorter (3.21 Å) and two longer (3.22 Å) Ce–Ge bond lengths. Ag is bonded in a 12-coordinate geometry to five Ce, one Ag, and four Ge atoms. The Ag–Ag bond length is 2.79 Å. There are a spread of Ag–Ge bond distances ranging from 2.63–2.80 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Ce, two equivalent Ag, and one Ge atom. The Ge–Ge bond length is 2.62 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three Ce and six equivalent Ag atoms.
