Materials Data on U6Co by Materials Project

Abstract

U6Co crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are four inequivalent U sites. In the first U site, U is bonded in a 4-coordinate geometry to four U and two equivalent Co atoms. There are a spread of U–U bond distances ranging from 2.80–3.32 Å. Both U–Co bond lengths are 2.78 Å. In the second U site, U is bonded in a distorted T-shaped geometry to thirteen U atoms. There are a spread of U–U bond distances ranging from 2.71–3.22 Å. In the third U site, U is bonded in a distorted T-shaped geometry to thirteen U atoms. There are a spread of U–U bond distances ranging from 2.72–3.33 Å. In the fourth U site, U is bonded in a 4-coordinate geometry to four U and two equivalent Co atoms. Both U–Co bond lengths are 2.77 Å. Co is bonded in a 10-coordinate geometry to eight U and two equivalent Co atoms. Both Co–Co bond lengths are 2.58 Å.
