The crystal structure described by InAl(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 Al(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 Al(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 Al(1)S4 tetrahedra. Al(1) is bonded to four equivalent S(1) atoms to form AlS4 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 Al(1) atom to form corner-sharing SAlInAg2 tetrahedra. is represented by the CIF file [CIF]
