Abstract: Highlights: [•] High-quality Ag2HgSnS4 single crystal has been synthesized. [•] Electronic structure of Ag2HgSnS4 has been studied by XPS and XES. [•] XPS data reveal low hygroscopicity of Ag2HgSnS4 surface. [•] Ag 4d states contribute predominantly in the central portion of the valence band. [•] S 3p states contribute mainly in the central and upper portions of the valence band. [ABSTRACT FROM AUTHOR]
