Materials Data on Nb3Co2Si by Materials Project
Nb3Co2Si crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Nb is bonded in a 6-coordinate geometry to four equivalent Co and two equivalent Si atoms. There are two shorter (2.68 Å) and two longer (2.75 Å) Nb–Co bond lengths. Both Nb–Si bond lengths are 2.77 Å. Co is bonded in a 12-coordinate geometry to six equivalent Nb, three equivalent Co, and three equivalent Si atoms. All Co–Co bond lengths are 2.61 Å. All Co–Si bond lengths are 2.42 Å. Si is bonded to six equivalent Nb and six equivalent Co atoms to form face-sharing SiNb6Co6 cuboctahedra.
