Materials Data on Lu(CoGe)2 by Materials Project

Lu(CoGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Lu is bonded in a 8-coordinate geometry to eight equivalent Co and eight equivalent Ge atoms. All Lu–Co bond lengths are 3.19 Å. All Lu–Ge bond lengths are 3.05 Å. Co is bonded to four equivalent Lu and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing CoLu4Ge4 tetrahedra. All Co–Ge bond lengths are 2.32 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Lu, four equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.53 Å.

Materials Data on LuCoGe2 by Materials Project

LuCoGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Lu is bonded in a 4-coordinate geometry to four equivalent Co and ten Ge atoms. All Lu–Co bond lengths are 3.11 Å. There are a spread of Lu–Ge bond distances ranging from 3.08–3.27 Å. Co is bonded in a 9-coordinate geometry to four equivalent Lu and five Ge atoms. There are one shorter (2.24 Å) and four longer (2.37 Å) Co–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Lu and four equivalent Co atoms. In the second Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Lu, one Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.53 Å.
