The crystal structure of the intercalation compounds AgxTaS2 (0≤x≤23) and AgxTiS2 (0≤x≤0.42) are reported. For both intercalated dichalcogenides only stages n=2 and 1 are observed and there is no evidence for higher staging. In stage 1 Ag23TaS2, the silver ions reside in tetrahedral sites and the 2Hb−TaS2 structure changes to that of MoS2. For stage 2 Ag13TaS2, we observe a six layer unit cell with the silver ions again in tetrahedral sites. In stage 1 Ag0.42TiS2 and stage 2 Ag0.2TiS2, the silver ions are in octahedral sites and there is no change of the host lattice stacking. The samples were prepared both thermally and electrolytically and the same lattice parameters were obtained in both cases.
