AgGaSSe is Stannite-like structured and crystallizes in the orthorhombic I2_12_12_1 space group. Ag(1) is bonded to two equivalent Se(1) and two equivalent S(1) atoms to form AgSe2S2 tetrahedra that share corners with four equivalent Ag(1)Se2S2 tetrahedra and corners with eight equivalent Ga(1)Se2S2 tetrahedra. Ga(1) is bonded to two equivalent Se(1) and two equivalent S(1) atoms to form GaSe2S2 tetrahedra that share corners with four equivalent Ga(1)Se2S2 tetrahedra and corners with eight equivalent Ag(1)Se2S2 tetrahedra. Se(1) is bonded to two equivalent Ag(1) and two equivalent Ga(1) atoms to form SeGa2Ag2 tetrahedra that share corners with four equivalent Se(1)Ga2Ag2 tetrahedra and corners with eight equivalent S(1)Ga2Ag2 tetrahedra. S(1) is bonded to two equivalent Ag(1) and two equivalent Ga(1) atoms to form SGa2Ag2 tetrahedra that share corners with four equivalent S(1)Ga2Ag2 tetrahedra and corners with eight equivalent Se(1)Ga2Ag2 tetrahedra.
