Materials Data on Gd2AlGe2 by Materials Project
Gd2AlGe2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to two equivalent Al and six equivalent Ge atoms. There are one shorter (3.25 Å) and one longer (3.28 Å) Gd–Al bond lengths. There are a spread of Gd–Ge bond distances ranging from 3.06–3.15 Å. Al is bonded in a 4-coordinate geometry to four equivalent Gd and four equivalent Ge atoms. There are two shorter (2.66 Å) and two longer (2.71 Å) Al–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to six equivalent Gd, two equivalent Al, and one Ge atom. The Ge–Ge bond length is 2.70 Å.
