Materials Data on Ce2CuGe6 by Materials Project
Ce2CuGe6 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 4-coordinate geometry to four equivalent Cu and ten Ge atoms. All Ce–Cu bond lengths are 3.17 Å. There are a spread of Ce–Ge bond distances ranging from 3.15–3.40 Å. In the second Ce site, Ce is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ce–Ge bond distances ranging from 3.04–3.21 Å. Cu is bonded in a 9-coordinate geometry to four equivalent Ce and five Ge atoms. There are a spread of Cu–Ge bond distances ranging from 2.36–2.44 Å. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ce, two equivalent Cu, and five Ge atoms. There are one shorter (2.49 Å) and four longer (2.93 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Ce, two equivalent Cu, and five Ge atoms. The Ge–Ge bond length is 2.50 Å. In the third Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Ce and five Ge atoms. All Ge–Ge bond lengths are 2.93 Å. In the fourth Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Ce and five Ge atoms. In the fifth Ge site, Ge is bonded in a 8-coordinate geometry to six Ce and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.56 Å. In the sixth Ge site, Ge is bonded in a 1-coordinate geometry to six Ce, one Cu, and two equivalent Ge atoms.
