Abstract

A new copper–silver–thiostannate, [enH][Cu₂AgSnS₄] (1), has been successfully synthesized under solvothermal conditions. Compound 1 features a quaternary two dimensional anionic [Cu₂AgSnS₄]⁻ layer, where Cu⁺ ions adopt a trigonal coordination mode and the Ag⁺ ion has a tetrahedral configuration. The photoelectrochemical studies indicate that 1 is photoactive and exhibits p-type semiconductor characteristics under visible light illumination.
