Title: Materials Data on USe2 by Materials Project

Abstract

USe2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. U4+ is bonded in a 9-coordinate geometry to nine Se2- atoms. There are a spread of U–Se bond distances ranging from 2.86–3.22 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to four equivalent U4+ atoms to form a mixture of distorted edge and corner-sharing SeU4 tetrahedra. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to five equivalent U4+ atoms.
