4-(2-Hydroxy­ethyl)-4H-1,2,4-triazole, an inter­mediate in the synthesis of iron–triazole spin-crossover compounds

The title 1,2,4-triazole derivative, C₄H₇N₃O, has been synthesized and characterized. Neighboring mol­ecules are connected by inter­molecular O—H...N hydrogen bonds, forming a linear chain arrangement along the crystallographic [101] direction.
