Materials Data on DyCoSi2 by Materials Project

Abstract

DyCoSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded in a 4-coordinate geometry to four equivalent Co and ten Si atoms. All Dy–Co bond lengths are 3.07 Å. There are a spread of Dy–Si bond distances ranging from 3.02–3.15 Å. Co is bonded in a 9-coordinate geometry to four equivalent Dy and five Si atoms. There are a spread of Co–Si bond distances ranging from 2.22–2.31 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 12-coordinate geometry to four equivalent Dy and four equivalent Co atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to six equivalent Dy, one Co, and two equivalent Si atoms. Both Si–Si bond lengths are 2.42 Å.
