Materials Data on Dy2(Al3Pd)3 by Materials Project

Dy2(PdAl3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded in a 11-coordinate geometry to six Pd and eleven Al atoms. There are two shorter (3.45 Å) and four longer (3.49 Å) Dy–Pd bond lengths. There are a spread of Dy–Al bond distances ranging from 3.06–3.20 Å. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 8-coordinate geometry to four equivalent Dy and eight Al atoms. There are a spread of Pd–Al bond distances ranging from 2.57–2.67 Å. In the second Pd site, Pd is bonded in a 8-coordinate geometry to four equivalent Dy and eight Al atoms. There are a spread of Pd–Al bond distances ranging from 2.57–2.66 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to two equivalent Dy and two equivalent Pd atoms. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Dy, three Pd, and one Al atom. The Al–Al bond length is 2.87 Å. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Dy, three Pd, and five Al atoms. There are one shorter (2.80 Å) and two longer (2.86 Å) Al–Al bond lengths. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Dy, two equivalent Pd, and two equivalent Al atoms.
