Abstract

Two new cuprous bromide phases Cu2(ImH)Br3 (Im = imidazole) (1) and Cu3(Trz)2Br3 (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 CuI phases from CuII reactants. UV/Vis spectroscopy and thermal analyses were performed on both materials.
