Two new cuprous bromide phases Cu 2 (ImH)Br 3 (Im = imidazole) ( 1 ) and Cu 3 (Trz) 2 Br 3 (Trz = 1,2,4‐triazole) ( 2 ) were synthesized by hydrothermal method and characterized by single‐crystal X‐ray diffraction. The compounds exhibit similar triclinic one‐dimensional crystal structures (space group P $\bar{1}$ ) but they are built from two different copper bromide chains. The influence of the azole ligands on the coordination of the transition metals is discussed. Zinc metal has been shown to be an effective reductant in hydrothermal conditions for stabilizing Cu I phases from Cu II reactants. UV/Vis spectroscopy and thermal analyses were performed on both materials.
