Materials Data on Dy6Co2Sn by Materials Project
Dy6Co2Sn crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 4-coordinate geometry to two Co and two Sn atoms. There are one shorter (2.71 Å) and one longer (3.20 Å) Dy–Co bond lengths. There are one shorter (3.09 Å) and one longer (3.34 Å) Dy–Sn bond lengths. In the second Dy site, Dy is bonded in a 5-coordinate geometry to three Co and two Sn atoms. There are two shorter (2.91 Å) and one longer (3.12 Å) Dy–Co bond lengths. There are one shorter (3.22 Å) and one longer (3.65 Å) Dy–Sn bond lengths. In the third Dy site, Dy is bonded in a 4-coordinate geometry to three Co and one Sn atom. There are one shorter (2.74 Å) and two longer (2.88 Å) Dy–Co bond lengths. The Dy–Sn bond length is 3.40 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 2-coordinate geometry to eight Dy atoms. In the second Co site, Co is bonded in a 9-coordinate geometry to eight Dy and one Co atom. The Co–Co bond length is 2.24 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a cuboctahedral geometry to twelve Dy atoms. In the second Sn site, Sn is bonded in a body-centered cubic geometry to eight Dy atoms.
