NdPrSb2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Nd(1) is bonded to six equivalent Sb(1) atoms to form NdSb6 octahedra that share corners with six equivalent Pr(1)Sb6 octahedra, edges with six equivalent Nd(1)Sb6 octahedra, and edges with six equivalent Pr(1)Sb6 octahedra. The corner-sharing octahedra are not tilted. Pr(1) is bonded to six equivalent Sb(1) atoms to form PrSb6 octahedra that share corners with six equivalent Nd(1)Sb6 octahedra, edges with six equivalent Nd(1)Sb6 octahedra, and edges with six equivalent Pr(1)Sb6 octahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded to three equivalent Nd(1) and three equivalent Pr(1) atoms to form a mixture of corner and edge-sharing SbPr3Nd3 octahedra. The corner-sharing octahedra are not tilted.
