AgIn5S8 is Spinel-like structured and crystallizes in the cubic F-43m space group. Ag(1) is bonded to four equivalent S(1) atoms to form AgS4 tetrahedra that share corners with twelve equivalent In(2)S6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent S(2) atoms to form corner-sharing InS4 tetrahedra. The corner-sharing octahedral tilt angles are 60°. In the second In site, In(2) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form InS6 octahedra that share corners with three equivalent Ag(1)S4 tetrahedra, corners with three equivalent In(1)S4 tetrahedra, and edges with six equivalent In(2)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Ag(1) and three equivalent In(2) atoms. In the second S site, S(2) is bonded to one In(1) and three equivalent In(2) atoms to form a mixture of distorted edge and corner-sharing SIn4 tetrahedra.
