Gd3Sb4 crystallizes in the cubic I-43d space group. Gd(1) is bonded to eight equivalent Sb(1) atoms to form a mixture of distorted edge, corner, and face-sharing GdSb8 hexagonal bipyramids. Sb(1) is bonded to six equivalent Gd(1) atoms to form a mixture of distorted edge, corner, and face-sharing SbGd6 octahedra. The corner-sharing octahedral tilt angles range from 15-51°.
Gd3Sb4 crystallizes in the cubic I-43d space group. Gd(1) is bonded to eight equivalent Sb(1) atoms to form a mixture of distorted edge, corner, and face-sharing GdSb8 hexagonal bipyramids. There are four shorter (3.19 Å) and four longer (3.23 Å) Gd(1)-Sb(1) bond lengths. Sb(1) is bonded to six equivalent Gd(1) atoms to form a mixture of distorted edge, corner, and face-sharing SbGd6 octahedra. The corner-sharing octahedral tilt angles range from 15-51°.
