Besides the oxides, oxocations
stabilise V
v as VO2
+, V
IV as VO
2+ and Ti
IV as TiO
2+ The ability of oxygen
to stabilise these high oxidation states exceeds that of fluorine Thus
the highest Mn fluoride is MnF4 whereas the highest oxide is Mn2O7 The ability of oxygen to form multiple bonds to metals explains its
superiority
