Materials Data on La2Co2Si by Materials Project
La2Co2Si crystallizes in the triclinic P-1 space group. The structure is three-dimensional. La is bonded in a 10-coordinate geometry to six equivalent Co and four equivalent Si atoms. There are a spread of La–Co bond distances ranging from 2.97–3.18 Å. There are a spread of La–Si bond distances ranging from 3.22–3.33 Å. Co is bonded in a 9-coordinate geometry to six equivalent La, two equivalent Co, and one Si atom. There are one shorter (2.32 Å) and one longer (2.37 Å) Co–Co bond lengths. The Co–Si bond length is 2.59 Å. Si is bonded in a distorted q6 geometry to eight equivalent La and two equivalent Co atoms.
