U5VSb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent U sites. In the first U site, U(1) is bonded to two equivalent V(1) and five equivalent Sb(1) atoms to form a mixture of distorted edge, face, and corner-sharing UV2Sb5 pentagonal bipyramids. In the second U site, U(2) is bonded in a 8-coordinate geometry to two equivalent U(2) and six equivalent Sb(1) atoms. V(1) is bonded to six equivalent U(1) atoms to form distorted face-sharing VU6 octahedra. Sb(1) is bonded in a 9-coordinate geometry to four equivalent U(2) and five equivalent U(1) atoms.

In the first U site, U(1) is bonded to two equivalent V(1) and five equivalent Sb(1) atoms to form a mixture of distorted edge, face, and corner-sharing UV2Sb5 pentagonal bipyramids. Both U(1)-V(1) bond lengths are 2.78 Å. There are a spread of U(1)-Sb(1) bond distances ranging from 3.09-3.27 Å. In the second U site, U(2) is bonded in a 8-coordinate geometry to two equivalent U(2) and six equivalent Sb(1) atoms. Both U(2)-U(2) bond lengths are 2.97 Å. All U(2)-Sb(1) bond lengths are 3.20 Å. V(1) is bonded to six equivalent U(1) atoms to form distorted face-sharing VU6 octahedra. Sb(1) is bonded in a 9-coordinate geometry to four equivalent U(2) and five equivalent U(1) atoms.
