Mesoionic 1,2,4-triazolium-3-thiolate compounds are silver halide stabilizers and fixing agents. They are useful in heat developable and heat stabilizable photographic silver halide materials. After imagewise exposure, developed and stabilized silver images are produced by heating the materials.

Two-coordinate gold(I) complexes involving mesoionic thiolate ligands have been synthesized, including homoleptic and mixed-ligand complexes. Many of these compounds have stability and solubility properties that are desirable for practical use as gold sensitizers for photographic silver halide dispersions.
