Coordination of carboxamido nitrogen

摘要

Although coordination of carboxamido nitrogen to Fe (III) center has been assumed to be improbable, research work during the past few years has demonstrated that Fe(III) complexes with ligated carboxamido nitrogens can be readily synthesized. The Fe(III)-N_amido bond distances lie in the range of 1.8-2.2 A in the various low spinand high spin Fe(III) complexes. These complexes are stable in aqueous Media and their redox parameters indicate that the carbox- Amido nitrogens provide significant stability to the Fe (III) Center.
