Materials Data on Ce2(SbPd3)3 by Materials Project

Abstract

Ce2(Pd3Sb)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 9-coordinate geometry to eleven Pd and six Sb atoms. There are a spread of Ce–Pd bond distances ranging from 3.06–3.62 Å. There are a spread of Ce–Sb bond distances ranging from 3.48–3.61 Å. There are four inequivalent Pd sites. In the first Pd site, Pd is bonded in a 5-coordinate geometry to two equivalent Ce, eight Pd, and three Sb atoms. There are a spread of Pd–Pd bond distances ranging from 2.83–3.21 Å. There are one shorter (2.70 Å) and two longer (2.85 Å) Pd–Sb bond lengths. In the second Pd site, Pd is bonded in a 12-coordinate geometry to two equivalent Ce, seven Pd, and two equivalent Sb atoms. There are one shorter (2.89 Å) and two longer (2.97 Å) Pd–Pd bond lengths. Both Pd–Sb bond lengths are 2.62 Å. In the third Pd site, Pd is bonded in a 12-coordinate geometry to three equivalent Ce, six Pd, and three Sb atoms. There are a spread of Pd–Pd bond distances ranging from 2.84–3.26 Å. There are a spread of Pd–Sb bond distances ranging from 2.66–2.90 Å. In the fourth Pd site, Pd is bonded in a 12-coordinate geometry to two equivalent Ce, eight Pd, and two equivalent Sb atoms. Both Pd–Sb bond lengths are 2.64 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded to four equivalent Ce and eight Pd atoms to form distorted face-sharing SbCe4Pd8 cuboctahedra. In the second Sb site, Sb is bonded in a 12-coordinate geometry to four equivalent Ce and eight Pd atoms.
