U3Sb4 crystallizes in the cubic I-43d space group. U(1) is bonded to eight equivalent Sb(1) atoms to form a mixture of distorted edge, corner, and face-sharing USb8 hexagonal bipyramids. Sb(1) is bonded to six equivalent U(1) atoms to form a mixture of distorted edge, corner, and face-sharing SbU6 octahedra. The corner-sharing octahedral tilt angles range from 15-51°.
U3Sb4 crystallizes in the cubic I-43d space group. U(1) is bonded to eight equivalent Sb(1) atoms to form a mixture of distorted edge, corner, and face-sharing USb8 hexagonal bipyramids. There are four shorter (3.16 Å) and four longer (3.24 Å) U(1)-Sb(1) bond lengths. Sb(1) is bonded to six equivalent U(1) atoms to form a mixture of distorted edge, corner, and face-sharing SbU6 octahedra. The corner-sharing octahedral tilt angles range from 15-51°.
