The material structure described by Cu2CoGeS4 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 Ge(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 Ge(1)S4 tetrahedra. Ge(1) is bonded to four equivalent S(1) atoms to form GeS4 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 Ge(1) atom to form corner-sharing SCoCu2Ge tetrahedra. is represented by the CIF card [CIF]
