Pr4Sb3 crystallizes in the cubic I-43d space group. Pr(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Sb(1) is bonded to eight equivalent Pr(1) atoms to form a mixture of distorted edge, face, and corner-sharing SbPr8 hexagonal bipyramids.
Pr4Sb3 crystallizes in the cubic I-43d space group. Pr(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. There are three shorter (3.19 Å) and three longer (3.46 Å) Pr(1)-Sb(1) bond lengths. Sb(1) is bonded to eight equivalent Pr(1) atoms to form a mixture of distorted edge, face, and corner-sharing SbPr8 hexagonal bipyramids.
