The compound described by SrNd3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to twelve equivalent Nd(1) atoms to form SrNd12 cuboctahedra that share corners with six equivalent Sr(1)Nd12 cuboctahedra, corners with twelve equivalent Nd(1)Sr4Nd8 cuboctahedra, edges with eighteen equivalent Nd(1)Sr4Nd8 cuboctahedra, faces with eight equivalent Sr(1)Nd12 cuboctahedra, and faces with twelve equivalent Nd(1)Sr4Nd8 cuboctahedra. Nd(1) is bonded to four equivalent Sr(1) and eight equivalent Nd(1) atoms to form distorted NdSr4Nd8 cuboctahedra that share corners with four equivalent Sr(1)Nd12 cuboctahedra, corners with fourteen equivalent Nd(1)Sr4Nd8 cuboctahedra, edges with six equivalent Sr(1)Nd12 cuboctahedra, edges with twelve equivalent Nd(1)Sr4Nd8 cuboctahedra, faces with four equivalent Sr(1)Nd12 cuboctahedra, and faces with sixteen equivalent Nd(1)Sr4Nd8 cuboctahedra. is represented by the CIF file [CIF]
