Materials Data on Yb3CoSn6 by Materials Project
Yb3CoSn6 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 12-coordinate geometry to two equivalent Co and ten Sn atoms. Both Yb–Co bond lengths are 3.55 Å. There are a spread of Yb–Sn bond distances ranging from 3.22–3.64 Å. In the second Yb site, Yb is bonded in a 11-coordinate geometry to one Co and ten Sn atoms. The Yb–Co bond length is 3.15 Å. There are a spread of Yb–Sn bond distances ranging from 3.19–3.34 Å. Co is bonded in a 10-coordinate geometry to five Yb and five Sn atoms. There are a spread of Co–Sn bond distances ranging from 2.51–2.58 Å. There are four inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to four Yb, one Co, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 3.02 Å. In the second Sn site, Sn is bonded in a 4-coordinate geometry to six Yb and one Sn atom. The Sn–Sn bond length is 2.99 Å. In the third Sn site, Sn is bonded in a 6-coordinate geometry to four Yb and two equivalent Co atoms. In the fourth Sn site, Sn is bonded in a 9-coordinate geometry to six Yb, one Co, and two equivalent Sn atoms.
