Materials Data on UCo2Sn by Materials Project
UCo2Sn crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. U is bonded in a 2-coordinate geometry to eight Co and five equivalent Sn atoms. There are a spread of U–Co bond distances ranging from 2.57–3.07 Å. There are a spread of U–Sn bond distances ranging from 3.18–3.25 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 8-coordinate geometry to four equivalent U and four equivalent Sn atoms. There are a spread of Co–Sn bond distances ranging from 2.66–2.85 Å. In the second Co site, Co is bonded in a 7-coordinate geometry to four equivalent U and three equivalent Sn atoms. There are one shorter (2.58 Å) and two longer (2.59 Å) Co–Sn bond lengths. Sn is bonded in a 12-coordinate geometry to five equivalent U and seven Co atoms.
