Materials Data on Sm2CuGe6 by Materials Project
Abstract
Sm2CuGe6 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 10-coordinate geometry to ten Ge atoms. There are eight shorter (3.06 Å) and two longer (3.23 Å) Sm–Ge bond lengths. In the second Sm site, Sm is bonded in a 4-coordinate geometry to four equivalent Cu and ten Ge atoms. All Sm–Cu bond lengths are 3.16 Å. There are a spread of Sm–Ge bond distances ranging from 3.13–3.38 Å. Cu is bonded in a 9-coordinate geometry to four equivalent Sm and five Ge atoms. There are a spread of Cu–Ge bond distances ranging from 2.35–2.44 Å. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Sm, two equivalent Cu, and five Ge atoms. There are one shorter (2.49 Å) and four longer (2.92 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Sm and five Ge atoms. All Ge–Ge bond lengths are 2.92 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Sm,more »
