The compound described by NdPr3 is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. Nd(1) is bonded to four equivalent Pr(2) and eight equivalent Pr(1) atoms to form NdPr12 cuboctahedra that share corners with four equivalent Nd(1)Pr12 cuboctahedra, corners with eight equivalent Pr(2)Pr8Nd4 cuboctahedra, edges with eight equivalent Nd(1)Pr12 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Nd4 cuboctahedra, faces with four equivalent Nd(1)Pr12 cuboctahedra, faces with six equivalent Pr(2)Pr8Nd4 cuboctahedra, and faces with eight equivalent Pr(1)Pr8Nd4 cuboctahedra. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to four equivalent Nd(1), four equivalent Pr(1), and four equivalent Pr(2) atoms to form PrPr8Nd4 cuboctahedra that share corners with twelve equivalent Pr(1)Pr8Nd4 cuboctahedra, edges with eight equivalent Nd(1)Pr12 cuboctahedra, edges with eight equivalent Pr(1)Pr8Nd4 cuboctahedra, edges with eight equivalent Pr(2)Pr8Nd4 cuboctahedra, faces with four equivalent Nd(1)Pr12 cuboctahedra, faces with four equivalent Pr(2)Pr8Nd4 cuboctahedra, and faces with ten equivalent Pr(1)Pr8Nd4 cuboctahedra. In the second Pr site, Pr(2) is bonded to four equivalent Nd(1) and eight equivalent Pr(1) atoms to form PrPr8Nd4 cuboctahedra that share corners with four equivalent Pr(2)Pr8Nd4 cuboctahedra, corners with eight equivalent Nd(1)Pr12 cuboctahedra, edges with eight equivalent Pr(2)Pr8Nd4 cuboctahedra, edges with sixteen equivalent Pr(1)Pr8Nd4 cuboctahedra, faces with four equivalent Pr(2)Pr8Nd4 cuboctahedra, faces with six equivalent Nd(1)Pr12 cuboctahedra, and faces with eight equivalent Pr(1)Pr8Nd4 cuboctahedra. is represented by the CIF file [CIF]
