Materials Data on NdCoSi2 by Materials Project

Abstract

NdCoSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Nd is bonded in a 4-coordinate geometry to four equivalent Co and ten Si atoms. All Nd–Co bond lengths are 3.16 Å. There are a spread of Nd–Si bond distances ranging from 3.09–3.21 Å. Co is bonded in a 9-coordinate geometry to four equivalent Nd and five Si atoms. There are a spread of Co–Si bond distances ranging from 2.26–2.36 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 8-coordinate geometry to four equivalent Nd and four equivalent Co atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to six equivalent Nd, one Co, and two equivalent Si atoms. Both Si–Si bond lengths are 2.48 Å.
