The material structure described by Ag3SI is (Cubic) Perovskite structured and crystallizes in the trigonal R32 space group. Ag(1) is bonded in a 3-coordinate geometry to two equivalent S(1) and one I(1) atom. S(1) is bonded to six equivalent Ag(1) atoms to form distorted corner-sharing SAg6 octahedra. The corner-sharing octahedral tilt angles are 25°. I(1) is bonded in a trigonal planar geometry to three equivalent Ag(1) atoms. is represented by the CIF card [CIF]
