Nd3Cd is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to four equivalent Nd(1), four equivalent Nd(2), and four equivalent Cd(1) atoms to form distorted NdNd8Cd4 cuboctahedra that share corners with twelve equivalent Nd(1)Nd8Cd4 cuboctahedra, edges with eight equivalent Nd(1)Nd8Cd4 cuboctahedra, edges with eight equivalent Cd(1)Nd12 cuboctahedra, faces with four equivalent Cd(1)Nd12 cuboctahedra, and faces with ten equivalent Nd(1)Nd8Cd4 cuboctahedra. In the second Nd site, Nd(2) is bonded in a distorted square co-planar geometry to eight equivalent Nd(1) and four equivalent Cd(1) atoms. Cd(1) is bonded to four equivalent Nd(2) and eight equivalent Nd(1) atoms to form CdNd12 cuboctahedra that share corners with four equivalent Cd(1)Nd12 cuboctahedra, edges with eight equivalent Cd(1)Nd12 cuboctahedra, edges with sixteen equivalent Nd(1)Nd8Cd4 cuboctahedra, faces with four equivalent Cd(1)Nd12 cuboctahedra, and faces with eight equivalent Nd(1)Nd8Cd4 cuboctahedra.
