Iron 1992

Mössbauer study of the autoxidation of ethylenediaminetetraacetato-ferrate(II)

“…In order to answer it, first, we have to recall the stability of these complexes. A careful search of the vast coordination chemistry literature of iron [27][28][29][30][31] reveals that certain ligands provide significant stabilisation to the +3 oxidation state while other ligands prefer to bind iron in the +2 state. It has been established that ligands with carboxylate [32,33] groups exhibit preference towards Fe III centres.…”

A New Cylindrical, Six-Membered Iron(III) Inclusion Cluster Consisting of Three Oxo-Bridged Diiron Subunits Linked by Carboxylate Bridges

“…We are interested in the systematic tuning of the chemical properties of coordination complexes to act as efficient catalysts for the activation and subsequent conversion of small molecules. During the course of such studies, the spontaneous self-assembling of molecular units can lead to the formation of unexpected supramolecular aggregates. − We have recently come across a six-membered Fe(III) cluster that consists of a rather unique combination of oxo and carboxylato bridging groups, by which a cylindrical inclusion cluster with sodium is formed. Although several carboxylate ligated iron clusters have been reported in the literature, − the cluster reported in this contribution exhibits significantly different bridging ligands and overall geometry.…”

“…Fascinating model complexes for iron-oxygen aggregation with up to 19 iron centers have been characterized − and reviewed by different groups. − Over the past several decades chemists have made progress in preparing molecules that provide three-dimensional structures intended to complement the properties of cationic 19,23-27 and anionic , molecules or atoms in order to encapsulate such species selectively.…”
