Abstract: The formation of β- and α-modifications of Cu(SCN)₂(NH₃)₂ from aq. solns. at different ratios of [NH₃]:[Cu(II)] and temps. was studied by the x-ray diffraction. At 20° and low NH₃ ratios, [NH₃]:[Cu(II)] = 7:1, the β-modification and at high NH₃ ratios, [NH₃]:[Cu(II)] = 25:1, the α-modification is formed. At higher temps., 30° and 40°, and at high NH₃ ratios, [NH₃]:Cu(II) = 3.5-47:1, only the β-modification is formed. These results agree with the theoretical data reported by Bersuker (1962).
