AgGaS2 is Ilmenite-like structured and crystallizes in the trigonal R3m space group. Ag(1) is bonded in a 4-coordinate geometry to one S(1) and three equivalent S(2) atoms. Ga(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form edge-sharing GaS6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Ag(1) and three equivalent Ga(1) atoms to form distorted corner-sharing SGa3Ag trigonal pyramids. In the second S site, S(2) is bonded in a 6-coordinate geometry to three equivalent Ag(1) and three equivalent Ga(1) atoms.
