The material structure described by Ag3SI is Hazelwoodite-derived structured and crystallizes in the trigonal R3 space group. Ag(1) is bonded in a 4-coordinate geometry to two equivalent S(1) and two equivalent I(1) atoms. S(1) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. I(1) is bonded in a 6-coordinate geometry to six equivalent Ag(1) atoms. is represented by the CIF card [CIF]
