Materials Data on CeAl4Co by Materials Project

Abstract

CeCoAl4 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. Ce is bonded in a 1-coordinate geometry to one Co and twelve Al atoms. The Ce–Co bond length is 2.88 Å. There are a spread of Ce–Al bond distances ranging from 3.08–3.25 Å. Co is bonded in a 9-coordinate geometry to one Ce and eight Al atoms. There are a spread of Co–Al bond distances ranging from 2.32–2.60 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to four equivalent Ce, two equivalent Co, and six Al atoms. There are a spread of Al–Al bond distances ranging from 2.74–3.00 Å. In the second Al site, Al is bonded in a distorted linear geometry to two equivalent Ce, two equivalent Co, and eight Al atoms. All Al–Al bond lengths are 2.79 Å. In the third Al site, Al is bonded in a 4-coordinate geometry to two equivalent Ce, two equivalent Co, and eight Al atoms.
