Vorschrift

For potassium (2,2'-bipyridine) oxodiperoxovanadium (V), vanadium pentoxide (0.91 g) and potassium hydroxide (0.65 g) are dissolved in water (10 ml), cooled, and, if necessary, the dissolution is completed with a small amount of hydrogen peroxide. To the clear, cooled solution, hydrogen peroxide (10 ml) and 2,2'-bipyridine (1.6 g) dissolved in ethanol (7-8 ml) are added. Pure crystals are obtained as described for the analogous oxalato-derivative of potassium. Potassium (1,10-phenanthroline) vanadium (V) can be obtained similarly.
