Cobalt and Copper Coordination Polymers Containing Acetylacetonato‐Derived Ligands and Bidentate Pyridine Coligands: Synthesis, Crystal Structures and Magnetic Properties

European Journal of Inorganic Chemistry (2008)

Javier Corcuera Atienza A. Gutiérrez M.F. Perpiñán A.E. Sánchez

Abstract One‐dimensional chain derivatives of the general formula [M(acac) 2 (μ‐bipyridine)] were obtained from (acetylacetonato)cobalt(II) or (trifluoromethylacetylacetonato)copper(II) derivatives and bipyridine‐like bridging ligands: 1,2‐bis(4‐pyridyl)ethane, 4,4′‐bpa ( 1 , Co; 2 , Cu), trans ‐1,2‐bis(4‐pyridyl)ethylene, 4,4′‐bpe ( 3 , Co; 4 , Cu), 1,2‐bis(2‐pyridyl)ethylene, 2,2′‐bpe ( 5 , Co) or pyrazine ( 7 , Cu). The reaction of the copper parent derivative with 2,2′‐bpe gives rise, however, to a dimeric species [{Cu(tfacac) 2 } 2 (μ‐2,2′‐bpe)] ( 6 ). Derivatives 4 – 7 were characterized by X‐ray crystallography, which showed linear ( 4 , 7 ) or zigzag chains ( 5 ), depending on the bipyridine ligand shape. In the chain complexes, the metal centre is six‐coordinate; the oxygen donor atoms of the acetylacetonato ligands occupy the equatorial positions and the bridging bipyridine ligands are in trans axial positions. Compound 6 forms a dimer with the two copper atoms in a square pyramidal environment, in which the nitrogen atoms of the bridging 2,2′‐bpe ligand occupy the apical position in each pyramid. Magnetic susceptibility studies of the cobalt compounds are dominated by the spin–orbit coupling characteristic of this metal ion. At low temperatures and in the copper derivatives, weak antiferromagnetic interactions along the chain were observed.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

Biological activity of Fe(iii) aquo-complexes towards ferric chelate reductase (FCR)

Organic & Biomolecular Chemistry (2011)

Rosa Escudero Mar Gómez‐Gallego Santiago Romano Israel Fernández A. Gutiérrez

In this study we have obtained experimental evidence that confirms the high activity of aquo complexes III and IV towards the enzyme FCR, responsible for the reduction of Fe(III) to Fe(II) in the process of iron acquisition by plants. The in vivo FCR assays in roots of stressed cucumber plants have shown a higher efficiency of the family of complexes III and a striking structure–activity relationship with the nature of the substituent placed in a phenyl group far away from the metal center. The results obtained in this work demonstrate that all the aquo compounds tested interact efficiently with the enzyme FCR and hence constitute a new concept of iron chelates that could be of great use in agronomy.
