The compound described by Yb4Sb3 crystallizes in the cubic I-43d space group. Yb(1) is bonded to six equivalent Sb(1) atoms to form a mixture of distorted corner, face, and edge-sharing YbSb6 octahedra. The corner-sharing octahedral tilt angles range from 17-50°. Sb(1) is bonded to eight equivalent Yb(1) atoms to form a mixture of distorted corner, face, and edge-sharing SbYb8 hexagonal bipyramids. is represented by the CIF card [CIF]
