The corner-sharing octahedra tilt angles range from 7–71°. There are a spread of U–S bond distances ranging from 2.67–2.77 Å. There are twelve inequivalent S2- sites. In the first S2- site, S2- is bonded to five U3+ atoms to form SU5 square pyramids that share corners with seven SU4 tetrahedra, edges with four SU5 square pyramids, and an edgeedge with one SU4 tetrahedra. In the second S2- site, S2- is bonded to five U3+ atoms to form SU5 square pyramids that share corners with seven SU4 tetrahedra, edges with four SU5 square pyramids, and an edgeedge with one SU4 tetrahedra. In the third S2- site, S2- is bonded in a 3-coordinate geometry to three U3+ atoms. In the fourth S2- site, S2- is bonded to five U3+ atoms to form SU5 square pyramids that share corners with seven SU4 tetrahedra, edges with four SU5 square pyramids, and an edgeedge with one SU4 tetrahedra. In the fifth S2- site, S2- is bonded to four U3+ atoms to form SU4 tetrahedra that share corners with seven SU5 square pyramids, corners with two equivalent SU4 tetrahedra, an edgeedge with one SU5 square pyramid, and edges with two equivalent SU4 tetrahedra. In the sixth S2- site, S2- is bonded to five U3+ atoms to form SU5 square pyramids that share corners with seven SU4 tetrahedra, edges with four SU5 square pyramids, and an edgeedge with one SU4 tetrahedra. In the seventh S2- site, S2- is bonded in a 3-coordinate geometry to three U3+ atoms.
