The material structure described by K3Dy is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent K(1), four equivalent K(2), and four equivalent Dy(1) atoms to form distorted KK8Dy4 cuboctahedra that share corners with twelve equivalent K(1)K8Dy4 cuboctahedra, edges with eight equivalent K(1)K8Dy4 cuboctahedra, edges with eight equivalent Dy(1)K12 cuboctahedra, faces with four equivalent Dy(1)K12 cuboctahedra, and faces with ten equivalent K(1)K8Dy4 cuboctahedra. In the second K site, K(2) is bonded in a distorted square co-planar geometry to eight equivalent K(1) and four equivalent Dy(1) atoms. Dy(1) is bonded to four equivalent K(2) and eight equivalent K(1) atoms to form DyK12 cuboctahedra that share corners with four equivalent Dy(1)K12 cuboctahedra, edges with eight equivalent Dy(1)K12 cuboctahedra, edges with sixteen equivalent K(1)K8Dy4 cuboctahedra, faces with four equivalent Dy(1)K12 cuboctahedra, and faces with eight equivalent K(1)K8Dy4 cuboctahedra. is represented by the CIF file [CIF]
