The material structure described by AgCuGa2Te4 is Stannite-like structured and crystallizes in the tetragonal I-4 space group. Ag(1) is bonded to four equivalent Te(1) atoms to form AgTe4 tetrahedra that share corners with four equivalent Cu(1)Te4 tetrahedra, corners with four equivalent Ga(1)Te4 tetrahedra, and corners with four equivalent Ga(2)Te4 tetrahedra. Cu(1) is bonded to four equivalent Te(1) atoms to form CuTe4 tetrahedra that share corners with four equivalent Ag(1)Te4 tetrahedra, corners with four equivalent Ga(1)Te4 tetrahedra, and corners with four equivalent Ga(2)Te4 tetrahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with four equivalent Ag(1)Te4 tetrahedra, corners with four equivalent Cu(1)Te4 tetrahedra, and corners with four equivalent Ga(2)Te4 tetrahedra. In the second Ga site, Ga(2) is bonded to four equivalent Te(1) atoms to form GaTe4 tetrahedra that share corners with four equivalent Ag(1)Te4 tetrahedra, corners with four equivalent Cu(1)Te4 tetrahedra, and corners with four equivalent Ga(1)Te4 tetrahedra. Te(1) is bonded to one Ag(1), one Cu(1), one Ga(1), and one Ga(2) atom to form corner-sharing TeGa2CuAg tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
