The crystal structure described by Cu2CoSiS4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Co(1) is bonded to four equivalent S(1) atoms to form CoS4 tetrahedra that share corners with four equivalent Si(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. Cu(1) is bonded to four equivalent S(1) atoms to form CuS4 tetrahedra that share corners with four equivalent Co(1)S4 tetrahedra, corners with four equivalent Cu(1)S4 tetrahedra, and corners with four equivalent Si(1)S4 tetrahedra. Si(1) is bonded to four equivalent S(1) atoms to form SiS4 tetrahedra that share corners with four equivalent Co(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. S(1) is bonded to one Co(1), two equivalent Cu(1), and one Si(1) atom to form corner-sharing SCoCu2Si tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
