Materials Data on Ce2Y(AlPd)3 by Materials Project

Abstract

Ce2Y(PdAl)3 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Ce is bonded in a 5-coordinate geometry to five Pd atoms. There are a spread of Ce–Pd bond distances ranging from 2.97–3.04 Å. Y is bonded in a 5-coordinate geometry to five Pd atoms. There are one shorter (2.98 Å) and four longer (3.01 Å) Y–Pd bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 9-coordinate geometry to four equivalent Ce, two equivalent Y, and three Al atoms. There are one shorter (2.82 Å) and two longer (2.83 Å) Pd–Al bond lengths. In the second Pd site, Pd is bonded in a 9-coordinate geometry to two equivalent Ce, one Y, and six Al atoms. There are four shorter (2.66 Å) and two longer (2.67 Å) Pd–Al bond lengths. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 4-coordinate geometry to four Pd atoms. In the second Al site, Al is bonded in a 12-coordinate geometry to four Pd atoms.
