The structure described by DySi2 is hexagonal omega structure-like structured and crystallizes in the tetragonal I4_1/amd space group. Dy(1) is bonded to twelve equivalent Si(1) atoms to form a mixture of face and edge-sharing DySi12 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
