Abstract

UCe2Se4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. U is bonded to eight equivalent Se atoms to form distorted USe8 hexagonal bipyramids that share corners with eight equivalent CeSe8 hexagonal bipyramids, edges with four equivalent USe8 hexagonal bipyramids, and faces with eight equivalent CeSe8 hexagonal bipyramids. There are four shorter (2.98 Å) and four longer (3.11 Å) U–Se bond lengths. Ce is bonded to eight equivalent Se atoms to form distorted CeSe8 hexagonal bipyramids that share corners with four equivalent USe8 hexagonal bipyramids, corners with four equivalent CeSe8 hexagonal bipyramids, edges with four equivalent CeSe8 hexagonal bipyramids, faces with four equivalent USe8 hexagonal bipyramids, and faces with four equivalent CeSe8 hexagonal bipyramids. There are a spread of Ce–Se bond distances ranging from 3.00–3.17 Å. Se is bonded to two equivalent U and four equivalent Ce atoms to form a mixture of distorted edge, face, and corner-sharing SeCe4U2 octahedra. The corner-sharing octahedra tilt angles range from 16–50°.
