Abstract

UThSb4 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. U6+ is bonded in a 9-coordinate geometry to nine Sb+2.50- atoms. There are a spread of U–Sb bond distances ranging from 3.11–3.26 Å. Th4+ is bonded in a 9-coordinate geometry to nine Sb+2.50- atoms. There are a spread of Th–Sb bond distances ranging from 3.20–3.36 Å. There are three inequivalent Sb+2.50- sites. In the first Sb+2.50- site, Sb+2.50- is bonded in a 8-coordinate geometry to two equivalent U6+, two equivalent Th4+, and four equivalent Sb+2.50- atoms. All Sb–Sb bond lengths are 3.09 Å. In the second Sb+2.50- site, Sb+2.50- is bonded to four equivalent U6+ and one Th4+ atom to form distorted SbThU4 square pyramids that share corners with four equivalent SbThU4 square pyramids, edges with four equivalent SbThU4 square pyramids, and edges with four equivalent SbTh4U trigonal bipyramids. In the third Sb+2.50- site, Sb+2.50- is bonded to one U6+ and four equivalent Th4+ atoms to form distorted SbTh4U trigonal bipyramids that share corners with four equivalent SbTh4U trigonal bipyramids, edges with four equivalent SbThU4 square pyramids, and edges with four equivalent SbTh4U trigonal bipyramids.
