3,5-Dimethyl-4H-1,2,4-triazole is an organic building block that can be used as a ligand. It can be employed in photochemical reactions with [M(CO)₆] (M = chromium, molybdenum, and tungsten) to prepare metal complexes. These complexes are stable in the solid state at low temperatures. In solution, the tungsten compound may also be handled in air, but the chromium and molybdenum compounds are slightly sensitive to air in solution. These compounds are soluble in polar solvents such as acetone and chlorinated solvents.
