Materials Data on Lu2CoGe2 by Materials Project
Lu2CoGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded in a 8-coordinate geometry to two equivalent Co and six Ge atoms. Both Lu–Co bond lengths are 3.10 Å. There are a spread of Lu–Ge bond distances ranging from 2.85–3.02 Å. In the second Lu site, Lu is bonded in a 2-coordinate geometry to four equivalent Co and seven Ge atoms. There are a spread of Lu–Co bond distances ranging from 2.99–3.03 Å. There are a spread of Lu–Ge bond distances ranging from 2.87–3.17 Å. Co is bonded in a 10-coordinate geometry to six Lu and four Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.37–2.54 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Lu, one Co, and one Ge atom. The Ge–Ge bond length is 2.65 Å. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Lu, three equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.74 Å.
