Two new quaternary thioarsenates(III), SrAg 4 As 2 S 6 ⋅2 H 2 O ( 1 ) and BaAgAsS 3 ( 2 ), have been prepared through a hydrazine‐hydrothermal method at low temperature. Compound 1 possesses a two‐dimensional (2D) layer network, while compound 2 features a one‐dimensional (1D) column structure. The detailed structure analysis indicates that Sr 2+ and Ba 2+ cations have different directing effects on the structures of thioarsenates(III). Both experimental and theoretical studies demonstrate that compounds 1 and 2 are narrow‐gap semiconductors. Our success in synthesizing these two quaternary thioarsenates(III) proves that the hydrazine‐hydrothermal technique is a powerful yet facile synthetic method for exploring new complex chalcogenides with diverse crystal structures and interesting physical properties.
