18 and 19 electron NO complexes with the [Fe'buS5'] moiety ('buS5'2- = dianion of 2,2′-bis-(2-mercapto-3,5-di-tertiary-butylphenylthio)diethylsulfide) have been isolated and converted reversibly into each other. The unpaired electron in meso-[Fe(NO)′buS5'], meso-1, is delocalized over the whole molecule and occupies an orbital that is antibonding with respect to Fe– N and Fe–S bonds. Consequently, the NO ligand is readily substituted under mild conditions. In contrast, the 18 electron complex meso-[Fe(NO)'buS5']PF6, meso-2, is entirely inert towards substitution. To our knowledge the exchange of NO by CO in meso-1 via meso-2 is the first example, in which NO is displaced by CO in an isolable NO complex. The NO release from meso-1 via meso-2 can be considered a model for reversible NO bonding in sulfur coordinated metal centres of nitrogenase. It is shown that one-electron redox reactions make stable Fe–NO bonds labile, and the reversible coordination and decoordination of NO in nitrogenase may be induced by a similar process.
