Materials Data on Al21Pd8 by Materials Project
Al21Pd8 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. there are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 10-coordinate geometry to ten Al atoms. There are a spread of Pd–Al bond distances ranging from 2.58–2.76 Å. In the second Pd site, Pd is bonded in a 10-coordinate geometry to ten Al atoms. There are a spread of Pd–Al bond distances ranging from 2.55–3.10 Å. There are six inequivalent Al sites. In the first Al site, Al is bonded to four equivalent Pd atoms to form distorted corner-sharing AlPd4 tetrahedra. In the second Al site, Al is bonded in a 3-coordinate geometry to three Pd atoms. In the third Al site, Al is bonded in a 3-coordinate geometry to four Pd atoms. In the fourth Al site, Al is bonded in a 4-coordinate geometry to four Pd atoms. In the fifth Al site, Al is bonded to four Pd atoms to form a mixture of distorted corner and edge-sharing AlPd4 tetrahedra. In the sixth Al site, Al is bonded in a 4-coordinate geometry to four Pd atoms.
