Materials Data on LuNiGe2 by Materials Project

LuNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to four equivalent Ni and ten Ge atoms. All Lu–Ni bond lengths are 3.11 Å. There are a spread of Lu–Ge bond distances ranging from 3.08–3.21 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Lu and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.28–2.40 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Lu, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.49 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Lu and four equivalent Ni atoms.
