Ir2S3

Ir₂S₃ is an iridium sulfide ceramic compound belonging to the transition metal chalcogenide family, characterized by mixed-valence iridium coordination with sulfide ligands. This material remains largely in the research and development phase, studied primarily for its electronic and catalytic properties in emerging applications such as electrochemistry, hydrogen evolution, and solid-state chemistry; its high density and potential for tunable electrical behavior make it of interest for exploratory applications where traditional oxides or sulfides are insufficient.
