Materials Data on TbCoSn by Materials Project
TbCoSn crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 10-coordinate geometry to four Co and six Sn atoms. There are a spread of Tb–Co bond distances ranging from 2.94–3.05 Å. There are a spread of Tb–Sn bond distances ranging from 3.12–3.28 Å. In the second Tb site, Tb is bonded in a 10-coordinate geometry to four Co and six Sn atoms. There are a spread of Tb–Co bond distances ranging from 2.95–3.05 Å. There are a spread of Tb–Sn bond distances ranging from 3.12–3.28 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 8-coordinate geometry to four Tb and four Sn atoms. There are three shorter (2.63 Å) and one longer (2.65 Å) Co–Sn bond lengths. In the second Co site, Co is bonded in a 8-coordinate geometry to four Tb and four Sn atoms. There are three shorter (2.63 Å) and one longer (2.65 Å) Co–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 10-coordinate geometry to six Tb and four Co atoms. In the second Sn site, Sn is bonded in a 10-coordinate geometry to six Tb and four Co atoms.
