Co(TlSe)2 is Matlockite-like structured and crystallizes in the tetragonal I4/mmm space group. The structure consists of two 7440-48-4 atoms inside a TlSe framework. In the TlSe framework, Tl(1) is bonded to four equivalent Se(1) atoms to form a mixture of corner and edge-sharing TlSe4 tetrahedra. Se(1) is bonded in a 5-coordinate geometry to four equivalent Tl(1) and one Se(1) atom.
