Abstract
White crystalline KCuF3 has been synthesized from the reaction of Cu(OH)2 with KHF2 and a small amount of 40% HF at pH ≤ 4, while the synthesis of blue fluoro(sulphato)cuprates(II), Na[CuF(SO4)]. 2H2O, K[CuF(SO4)].3H2O and NH4[CuF (SO4)].3H2O, has been accomplished by reacting Cu(OH)2 with AF and A2SO4 (A = Na, K or NH4), in the ratio of 1:1:1, in the presence of a small amount of 40% HF. Alternative synthesis of the latter involving reactions among Cu(OH)2, F-, and SCN-, and H2O2 or SO2(g) and H2O2 gave CuSCN and Cu11[Cu1SO3]2. 2H2O, respectively, instead of the desired product. The compounds have been characterized by elemental analyses, chemical determination of the oxidation state of copper, magnetic susceptibility and ESR measurements, IR, laser Raman (LR), and electronic spectroscopic studies. The complex [CuF(SO4)]- species has a distorted octahedral polymeric structure containing both F- and SO42- as bridging ligands.
