Materials Data on UCu2Sn by Materials Project
UCu2Sn crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. U is bonded in a 12-coordinate geometry to six equivalent Cu and six equivalent Sn atoms. There are four shorter (2.83 Å) and two longer (2.86 Å) U–Cu bond lengths. There are two shorter (3.34 Å) and four longer (3.37 Å) U–Sn bond lengths. Cu is bonded in a 8-coordinate geometry to three equivalent U, one Cu, and four equivalent Sn atoms. The Cu–Cu bond length is 2.33 Å. There are a spread of Cu–Sn bond distances ranging from 2.80–2.96 Å. Sn is bonded in a 2-coordinate geometry to six equivalent U and eight equivalent Cu atoms.
