UP2S7 crystallizes in the orthorhombic Fddd space group. U(1) is bonded in a 8-coordinate geometry to two equivalent S(2), two equivalent S(3), and four equivalent S(1) atoms. P(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form corner-sharing PS4 tetrahedra. There are four inequivalent S sites. In the first S site, S(3) is bonded in an L-shaped geometry to one U(1) and one P(1) atom. In the second S site, S(4) is bonded in a water-like geometry to two equivalent P(1) atoms. In the third S site, S(1) is bonded in a 3-coordinate geometry to two equivalent U(1) and one P(1) atom. In the fourth S site, S(2) is bonded in an L-shaped geometry to one U(1) and one P(1) atom.
UP2S7 crystallizes in the orthorhombic Fddd space group. U(1) is bonded in a 8-coordinate geometry to two equivalent S(2), two equivalent S(3), and four equivalent S(1) atoms. Both U(1)-S(2) bond lengths are 2.82 Å. Both U(1)-S(3) bond lengths are 2.80 Å. There are two shorter (2.88 Å) and two longer (2.94 Å) U(1)-S(1) bond lengths. P(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form corner-sharing PS4 tetrahedra. The P(1)-S(1) bond length is 2.07 Å. The P(1)-S(2) bond length is 2.03 Å. The P(1)-S(3) bond length is 2.02 Å. The P(1)-S(4) bond length is 2.14 Å. There are four inequivalent S sites.
