Materials Data on U3(Al3Co)4 by Materials Project
Abstract
U3(CoAl3)4 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. U is bonded in a 5-coordinate geometry to two equivalent U, four equivalent Co, and eleven Al atoms. Both U–U bond lengths are 3.25 Å. All U–Co bond lengths are 3.23 Å. There are a spread of U–Al bond distances ranging from 2.92–3.21 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to eight Al atoms. There are two shorter (2.33 Å) and six longer (2.48 Å) Co–Al bond lengths. In the second Co site, Co is bonded in a 12-coordinate geometry to four equivalent U and eight Al atoms. There are a spread of Co–Al bond distances ranging from 2.47–2.63 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to two equivalent U, two equivalent Co, and eight Al atoms. There are a spread of Al–Al bond distances ranging from 2.75–2.85 Å. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent U, three Co, and two equivalent Al atoms. In the third Al site, Al is bonded in a 3-coordinatemore »
