Materials Data on UPt by Materials Project

Abstract

UPt 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 Pt atoms. There are a spread of U–Pt bond distances ranging from 2.83–3.10 Å. In the second U site, U is bonded in a 5-coordinate geometry to seven Pt atoms. There are a spread of U–Pt bond distances ranging from 2.87–3.26 Å. In the third U site, U is bonded in a 7-coordinate geometry to seven Pt atoms. There are a spread of U–Pt bond distances ranging from 2.83–3.08 Å. In the fourth U site, U is bonded in a 7-coordinate geometry to seven Pt atoms. There are a spread of U–Pt bond distances ranging from 2.88–3.23 Å. There are four inequivalent Pt sites. In the first Pt site, Pt is bonded in a 7-coordinate geometry to seven U and one Pt atom. The Pt–Pt bond length is 3.16 Å. In the second Pt site, Pt is bonded in a 5-coordinate geometry to seven U and three Pt atoms. There are one shorter (3.04 Å) and one longer (3.05 Å) Pt–Pt bond lengths. In the third Pt site, Pt is bonded in a 7-coordinate geometry to seven U and one Pt atom. In the fourth Pt site, Pt is bonded in a 7-coordinate geometry to seven U and one Pt atom.
