Materials Data on Ce3CoGe2 by Materials Project

Abstract

Ce3CoGe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Ce sites. In the first Ce site, Ce is bonded in a 6-coordinate geometry to one Co and five Ge atoms. The Ce–Co bond length is 2.91 Å. There are a spread of Ce–Ge bond distances ranging from 2.98–3.28 Å. In the second Ce site, Ce is bonded in a 7-coordinate geometry to two equivalent Co and five Ge atoms. Both Ce–Co bond lengths are 2.81 Å. There are a spread of Ce–Ge bond distances ranging from 3.00–3.48 Å. In the third Ce site, Ce is bonded in a 8-coordinate geometry to three equivalent Co and five Ge atoms. There are two shorter (2.98 Å) and one longer (3.04 Å) Ce–Co bond lengths. There are a spread of Ce–Ge bond distances ranging from 3.00–3.07 Å. Co is bonded in a 9-coordinate geometry to six Ce and three Ge atoms. There are one shorter (2.51 Å) and two longer (2.54 Å) Co–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Ce and two equivalent Co atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to eight Ce and one Co atom.
