Materials Data on YbAlPd by Materials Project

YbPdAl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb is bonded in a 5-coordinate geometry to five equivalent Pd and six equivalent Al atoms. There are a spread of Yb–Pd bond distances ranging from 2.97–3.11 Å. There are a spread of Yb–Al bond distances ranging from 3.17–3.36 Å. Pd is bonded in a 9-coordinate geometry to five equivalent Yb and four equivalent Al atoms. There are a spread of Pd–Al bond distances ranging from 2.61–2.71 Å. Al is bonded to six equivalent Yb and four equivalent Pd atoms to form a mixture of distorted edge, corner, and face-sharing AlYb6Pd4 tetrahedra.

Materials Data on YbAl2Pd by Materials Project

YbPdAl2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Yb is bonded in a 1-coordinate geometry to three equivalent Pd and ten equivalent Al atoms. There are one shorter (2.79 Å) and two longer (3.07 Å) Yb–Pd bond lengths. There are a spread of Yb–Al bond distances ranging from 3.17–3.34 Å. Pd is bonded in a 9-coordinate geometry to three equivalent Yb and six equivalent Al atoms. There are two shorter (2.58 Å) and four longer (2.65 Å) Pd–Al bond lengths. Al is bonded in a distorted trigonal non-coplanar geometry to five equivalent Yb and three equivalent Pd atoms.
