Hg₃Se₂Cl₂ is a mixed-halide mercury selenide ceramic compound combining mercury, selenium, and chlorine elements. This is a research-stage material belonging to the family of mercury chalcogenide ceramics, which are of interest for their unique electronic and optical properties stemming from the heavy-metal chalcogen bonding system. Potential applications lie in specialized optoelectronic devices, infrared sensing, and semiconductor research where the combination of selenium and chlorine modifies the electronic bandgap and structural properties compared to simpler binary compounds.
