Materials Data on UIr by Materials Project

Abstract

UIr crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent U sites. In the first U site, U is bonded in a 7-coordinate geometry to seven Ir atoms. There are a spread of U–Ir bond distances ranging from 2.79–3.06 Å. In the second U site, U is bonded in a 5-coordinate geometry to six Ir atoms. There are a spread of U–Ir bond distances ranging from 2.80–3.18 Å. In the third U site, U is bonded in a 7-coordinate geometry to seven Ir atoms. There are a spread of U–Ir bond distances ranging from 2.81–3.05 Å. In the fourth U site, U is bonded in a 5-coordinate geometry to seven Ir atoms. There are a spread of U–Ir bond distances ranging from 2.81–3.23 Å. There are four inequivalent Ir sites. In the first Ir site, Ir is bonded in a 7-coordinate geometry to seven U atoms. In the second Ir site, Ir is bonded in a 5-coordinate geometry to six U atoms. In the third Ir site, Ir is bonded in a 7-coordinate geometry to seven U atoms. In the fourth Ir site, Ir is bonded in a 5-coordinate geometry to seven U atoms.
