The reaction of hydrazine with copperII chloride in acidic aqueous solution has been shown to produce at least four distinct complexes. Hydrazine behaves as a reducing agent, leading to the white, diamagnetic copperI complex N2H4CuCl and the black paramagnetic mixed-valence copperI,I,II complex N2H52Cu2Cl6. Blue and green copperII complexes N2H52CuCl4 2H2O and N2H5 CuCl3 are also formed. Infrared spectra establish the presence of coordinated hydrazinium ions in the blue, green, and black compounds. Structures are proposed for all of these materials based on spectroscopic and magnetic measurements.
