Materials Data on DyCoSn2 by Materials Project

Abstract

DyCoSn2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded in a 12-coordinate geometry to four equivalent Co and ten Sn atoms. All Dy–Co bond lengths are 3.31 Å. There are a spread of Dy–Sn bond distances ranging from 3.29–3.73 Å. Co is bonded in a 9-coordinate geometry to four equivalent Dy and five Sn atoms. There are a spread of Co–Sn bond distances ranging from 2.42–2.57 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 12-coordinate geometry to four equivalent Dy and four equivalent Co atoms. In the second Sn site, Sn is bonded in a 1-coordinate geometry to six equivalent Dy, one Co, and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.84 Å.
