K2Ti(CuS2)2 crystallizes in the tetragonal P4_2/mcm space group. K(1) is bonded in a body-centered cubic geometry to eight equivalent S(1) atoms. Ti(1) is bonded to four equivalent S(1) atoms to form TiS4 tetrahedra that share edges with four equivalent Cu(1)S4 tetrahedra. Cu(1) is bonded to four equivalent S(1) atoms to form distorted CuS4 tetrahedra that share corners with four equivalent Cu(1)S4 tetrahedra and edges with two equivalent Ti(1)S4 tetrahedra. S(1) is bonded in a 7-coordinate geometry to four equivalent K(1), one Ti(1), and two equivalent Cu(1) atoms.
