AgCd2GaS4 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. Ag(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form AgS4 tetrahedra that share corners with four equivalent Ga(1)S4 tetrahedra and corners with eight equivalent Cd(1)S4 tetrahedra. Cd(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form CdS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Cd(1)S4 tetrahedra, and corners with four equivalent Ga(1)S4 tetrahedra. Ga(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form GaS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra and corners with eight equivalent Cd(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Ag(1), two equivalent Cd(1), and one Ga(1) atom to form corner-sharing SCd2GaAg tetrahedra. In the second S site, S(2) is bonded to one Ag(1), two equivalent Cd(1), and one Ga(1) atom to form corner-sharing SCd2GaAg tetrahedra. In the third S site, S(3) is bonded to one Ag(1), two equivalent Cd(1), and one Ga(1) atom to form corner-sharing SCd2GaAg tetrahedra.
