Materials Data on Nd6Co2Sn by Materials Project
Nd6Co2Sn crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are three inequivalent Nd sites. In the first Nd site, Nd is bonded in a 4-coordinate geometry to two Co and two Sn atoms. There are one shorter (2.82 Å) and one longer (3.43 Å) Nd–Co bond lengths. There are one shorter (3.17 Å) and one longer (3.48 Å) Nd–Sn bond lengths. In the second Nd site, Nd is bonded in a 5-coordinate geometry to three Co and two Sn atoms. There are two shorter (2.98 Å) and one longer (3.23 Å) Nd–Co bond lengths. There are one shorter (3.33 Å) and one longer (3.79 Å) Nd–Sn bond lengths. In the third Nd site, Nd is bonded in a 4-coordinate geometry to three Co and one Sn atom. There are one shorter (2.85 Å) and two longer (2.97 Å) Nd–Co bond lengths. The Nd–Sn bond length is 3.52 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 2-coordinate geometry to eight Nd atoms. In the second Co site, Co is bonded in a 9-coordinate geometry to eight Nd and one Co atom. The Co–Co bond length is 2.26 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a cuboctahedral geometry to twelve Nd atoms. In the second Sn site, Sn is bonded in a body-centered cubic geometry to eight Nd atoms.
