Gd4Sb3 crystallizes in the cubic I-43d space group. Gd(1) is bonded to six equivalent Sb(1) atoms to form a mixture of distorted face, corner, and edge-sharing GdSb6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°. Sb(1) is bonded to eight equivalent Gd(1) atoms to form a mixture of distorted face, corner, and edge-sharing SbGd8 hexagonal bipyramids.

The corner-sharing octahedral tilt angles range from 18-49°. There are three shorter (3.13 Å) and three longer (3.33 Å) Gd(1)-Sb(1) bond lengths. Sb(1) is bonded to eight equivalent Gd(1) atoms to form a mixture of distorted face, corner, and edge-sharing SbGd8 hexagonal bipyramids.
