Materials Data on UBi2 by Materials Project

UBi2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. U is bonded in a 9-coordinate geometry to nine Bi atoms. There are a spread of U–Bi bond distances ranging from 3.24–3.40 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded in a 8-coordinate geometry to four equivalent U and four equivalent Bi atoms. All Bi–Bi bond lengths are 3.17 Å. In the second Bi site, Bi is bonded to five equivalent U atoms to form a mixture of edge and corner-sharing BiU5 square pyramids.
