The material described by AgCrS2 is Ilmenite-like structured and crystallizes in the trigonal R3m space group. Cr(1) is bonded in a 6-coordinate geometry to three equivalent S(1) and three equivalent S(2) atoms. Ag(1) is bonded in a 4-coordinate geometry to one S(1) and three equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Cr(1) and one Ag(1) atom. In the second S site, S(2) is bonded in a 6-coordinate geometry to three equivalent Cr(1) and three equivalent Ag(1) atoms. is represented by the CIF card [CIF]
