AgFeS2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Fe(1) is bonded to four equivalent S(1) atoms to form FeS4 tetrahedra that share corners with four equivalent Fe(1)S4 tetrahedra and corners with eight equivalent Ag(1)S4 tetrahedra. Ag(1) is bonded to four equivalent S(1) atoms to form AgS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra and corners with eight equivalent Fe(1)S4 tetrahedra. S(1) is bonded to two equivalent Fe(1) and two equivalent Ag(1) atoms to form corner-sharing SFe2Ag2 tetrahedra.
