Summary Light pink-white microcrystalline ammonium and potassium fluoromonooxalatomanganates(II), A[MnF(C2O4)] (A = NH4 or K), and sodium fluoromonooxalatomanganate(II) dihydrate, Na[MnF(C2O4)] · 2H2O, have been synthesized by two different methods. Either KMnO4 is reduced in the presence of 40% HF and alkali metal oxalate, A2C2O4 (A = NH4, Na or K), or MnO(OH) in 40% HF reacts with A2C2O4. Characterisation was made by elemental analyses, determination of oxidation states, magnetic susceptibility measurements and infrared spectral studies. 相似文献

Conclusions The authors have synthesized anilinium chloranilate (NH3C6H5)2(C6O4Cl2) (I) and acid ammonium chloranilate dihydrate NH4H5O2(C6O4C12) (II). By x-ray structural analysis they have established their crystal structures. In crystals of NH4H5O2(C6O4Cl2) they find the ion H5O
