InGa(AgS2)2 is Stannite-like structured and crystallizes in the tetragonal I-4 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent S(1) atoms to form AgS4 tetrahedra that share corners with four equivalent Ag(2)S4 tetrahedra, corners with four equivalent In(1)S4 tetrahedra, and corners with four equivalent Ga(1)S4 tetrahedra. In the second Ag site, Ag(2) is bonded to four equivalent S(1) atoms to form AgS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent In(1)S4 tetrahedra, and corners with four equivalent Ga(1)S4 tetrahedra. In(1) is bonded to four equivalent S(1) atoms to form InS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Ag(2)S4 tetrahedra, and corners with four equivalent Ga(1)S4 tetrahedra. Ga(1) is bonded to four equivalent S(1) atoms to form GaS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Ag(2)S4 tetrahedra, and corners with four equivalent In(1)S4 tetrahedra. S(1) is bonded to one Ag(1), one Ag(2), one In(1), and one Ga(1) atom to form corner-sharing SInGaAg2 tetrahedra.
