The crystal structure described by NdPr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Nd(1) is bonded to six equivalent Nd(1) and six equivalent Pr(1) atoms to form NdPr6Nd6 cuboctahedra that share corners with eighteen equivalent Nd(1)Pr6Nd6 cuboctahedra, edges with six equivalent Nd(1)Pr6Nd6 cuboctahedra, edges with twelve equivalent Pr(1)Pr6Nd6 cuboctahedra, faces with eight equivalent Nd(1)Pr6Nd6 cuboctahedra, and faces with twelve equivalent Pr(1)Pr6Nd6 cuboctahedra.
