Metal–organic framework encourages iron centre in ferrocene to oxidise

On binding oxygen, ferrocene bends and stretches, and alters its electronic structure

The iron atom at the centre of ferrocene has been oxidised for the first time. A metal–organic framework (MOF) facilitates the transformation, which converts ferrocene into a stretched, high-spin state that can accept oxygen from the air.
