Materials Data on Dy2AlGe2 by Materials Project

AlDy2Ge2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Dy is bonded in a 6-coordinate geometry to six equivalent Ge atoms. There are two shorter (2.89 Å) and four longer (3.06 Å) Dy–Ge bond lengths. Al is bonded in a distorted square co-planar geometry to four equivalent Ge atoms. All Al–Ge bond lengths are 2.76 Å. Ge is bonded in a 9-coordinate geometry to six equivalent Dy, two equivalent Al, and one Ge atom. The Ge–Ge bond length is 2.57 Å.
