Pr2Nd2Sb3 crystallizes in the cubic I2_13 space group. Nd(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Pr(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Sb(1) is bonded to four equivalent Nd(1) and four equivalent Pr(1) atoms to form a mixture of distorted edge, face, and corner-sharing SbPr4Nd4 hexagonal bipyramids.
Pr2Nd2Sb3 crystallizes in the cubic I2_13 space group. Nd(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. There are three shorter (3.17 Å) and three longer (3.44 Å) Nd(1)-Sb(1) bond lengths. Pr(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. There are three shorter (3.18 Å) and three longer (3.45 Å) Pr(1)-Sb(1) bond lengths. Sb(1) is bonded to four equivalent Nd(1) and four equivalent Pr(1) atoms to form a mixture of distorted edge, face, and corner-sharing SbPr4Nd4 hexagonal bipyramids.
