Copper azine compounds: Synthesis, structure and magnetic analyses of Cu(phenazine)Cl2, (phenazinium)2CuCl4 · H2O, and [Cu(phenazine)Cl2 · H2O]2

Three compounds composed of phenazine and copper chloride have been prepared and studied by infrared spectroscopy, X-ray diffraction, and variable temperature magnetization. The compounds synthesized and studied are: Cu(phenazine)Cl2 (1), (phenazinium)2CuCl4 · H2O (2), and [Cu(phenazine)Cl2 · H2O]2 (3). Compounds 1 and 2 are described as antiferromagnetic Heisenberg chains with exchange constants ∣J∣/kB = 33.8 K and 8.6 K, respectively.
