A general method for the electrosynthesis of anionic fluoro complexes of transition metals has been developed by the oxidation of sacrificial metal anodes in 20% HF medium at room temperature and at an applied potential of 2-8 V. Some mixed-valent complexes, e.g. Fe2F5.2H2O and Fe2F5.7H2O, have also been obtained by the same method. K2[MnF5].H2O was obtained by subsequent electrolytic oxidation of the Mn(II) fluoro complex obtained in situ in the first step. The method is rapid and gives a good yield with high purity.
