Thermally unstable Xe(SO3F)2 has been prepared by the reaction of XeF2 with HSO3F. Single crystals were obtained from HSO3F by slow cooling in a sealed tube. The molecular structure is characterized by the Xe atom covalently bonded to two O atoms of

For the first time the crystal structure of a permethylated metallocene anion has been obtained. The 17 valence electron complex decamethylmanganocene Cp*2Mn is reduced by molten potassium in THF to its extremely air-sensitive anion [Cp*2Mn]−. The

Fluorinated and otherwise substituted benzenes and also ferrocenes can be oxidized by fluorine containing oxidizers of different oxidative strength, resulting in salts of radical cations and occasionally even dications. These are identified with the

The 16-valence electron species [Cp*2 Fe]2+ (Cp*=η-C5 Me5 ), formally featuring a tetravalent iron ion, quantitatively binds CO in HF solution to form the stable, diamagnetic carbonyl species [Cp*2 Fe(CO)]2+ . This dication forms salts in the presen
