The crystal structure described by TiDySi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Ti(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted corner and edge-sharing TiSi4 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent Dy(1) and four equivalent Ti(1) atoms. is represented by the CIF file [CIF]
