The crystal structure described by US2 crystallizes in the monoclinic C2 space group. There are three inequivalent U sites. In the first U site, U(1) is bonded in a 10-coordinate geometry to one S(1), one S(3), one S(6), two equivalent S(2), two equivalent S(5), and three equivalent S(4) atoms. In the second U site, U(2) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(4), and two equivalent S(5) atoms. In the third U site, U(3) is bonded in a 10-coordinate geometry to one S(3), one S(4), one S(6), two equivalent S(2), two equivalent S(5), and three equivalent S(1) atoms. There are six inequivalent S sites. In the first S site, S(1) is bonded to one U(1), one U(2), and three equivalent U(3) atoms to form a mixture of distorted corner, face, and edge-sharing SU5 trigonal bipyramids. In the second S site, S(2) is bonded to one U(2), two equivalent U(1), and two equivalent U(3) atoms to form a mixture of distorted corner, face, and edge-sharing SU5 trigonal bipyramids. In the third S site, S(3) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent U(3), and two equivalent S(6) atoms. In the fourth S site, S(4) is bonded to one U(2), one U(3), and three equivalent U(1) atoms to form a mixture of distorted corner, face, and edge-sharing SU5 trigonal bipyramids. In the fifth S site, S(5) is bonded to one U(2), two equivalent U(1), and two equivalent U(3) atoms to form a mixture of distorted corner, face, and edge-sharing SU5 trigonal bipyramids. In the sixth S site, S(6) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent U(3), and two equivalent S(3) atoms. is represented by the CIF file [CIF]
