Pseudohalides thiocyanate ion

The thermal oxidation of thiocyanate by Fe(III) in a perchlorate medium involves two thiocyanato complexes of Fe(III) . The stoichiometry is thought to be 

Reaction (61) implies that the transition state contains 3 SCN ions. A steady state approximation for [ (SCN)2 ] leads to the observed rate law. A temperature variation study of /fj and is included in this paper. It was also concluded that simple redox breakdown of FeSCN is of negligible importance.
