The compound described by AcNd3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded to twelve equivalent Nd(1) atoms to form AcNd12 cuboctahedra that share corners with six equivalent Ac(1)Nd12 cuboctahedra, corners with twelve equivalent Nd(1)Ac4Nd8 cuboctahedra, edges with eighteen equivalent Nd(1)Ac4Nd8 cuboctahedra, faces with eight equivalent Ac(1)Nd12 cuboctahedra, and faces with twelve equivalent Nd(1)Ac4Nd8 cuboctahedra. Nd(1) is bonded to four equivalent Ac(1) and eight equivalent Nd(1) atoms to form NdAc4Nd8 cuboctahedra that share corners with four equivalent Ac(1)Nd12 cuboctahedra, corners with fourteen equivalent Nd(1)Ac4Nd8 cuboctahedra, edges with six equivalent Ac(1)Nd12 cuboctahedra, edges with twelve equivalent Nd(1)Ac4Nd8 cuboctahedra, faces with four equivalent Ac(1)Nd12 cuboctahedra, and faces with sixteen equivalent Nd(1)Ac4Nd8 cuboctahedra. is represented by the CIF card [CIF]
