The crystal structure described by SmNd3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sm(1) is bonded to twelve equivalent Nd(1) atoms to form SmNd12 cuboctahedra that share corners with twelve equivalent Sm(1)Nd12 cuboctahedra, edges with twenty-four equivalent Nd(1)Nd8Sm4 cuboctahedra, faces with six equivalent Sm(1)Nd12 cuboctahedra, and faces with twelve equivalent Nd(1)Nd8Sm4 cuboctahedra. Nd(1) is bonded to four equivalent Sm(1) and eight equivalent Nd(1) atoms to form NdNd8Sm4 cuboctahedra that share corners with twelve equivalent Nd(1)Nd8Sm4 cuboctahedra, edges with eight equivalent Sm(1)Nd12 cuboctahedra, edges with sixteen equivalent Nd(1)Nd8Sm4 cuboctahedra, faces with four equivalent Sm(1)Nd12 cuboctahedra, and faces with fourteen equivalent Nd(1)Nd8Sm4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
