“…1.63 V vs FcH/FcH + (preliminary assigned to anionic nitrate oxidation). The data obtained in this data article, compares well with available published data on some of the redox events for some of the complexes, namely complex 1 [5] , [6] , [7] , [8] , [9] , [10] , complex 2 [11] , [12] , [13] and complex 5 [11] ; obtained under different experimental conditions (different solvents, scan rates and supporting electrolytes). The linear responses obtained for the graphs of the peak currents vs the square root of the scan rate, for three main redox events in the CV of complex 1 (see Fig.…”

The data presented in this article is related to the research article entitled “Electrochemical and electronic properties of a series of substituted polypyridine ligands and their Co(II) complexes” (Ferreira et al., 2019). This data article presents electrochemical data of five polypyridine ligands, as well as of the three redox couples of each of their corresponding five polypyridine-containing Co(II) complexes. All complexes exhibit two Co-based redox couples (CoIII/II and CoII/I), as well as a ligand-based reduction of the Co(I) complex.

“…However the potential at which reduction occurs is very low, resulting in species that are extremely air sensitive and often contaminated with metallic iron. 16 By using more electron deficient ligands, 18, 19 it may be possible to move such switching events to a more accessible potential window giving species with greater potential application in molecular devices.…”

An electron transfer driven magnetic switch: ferromagnetic exchange and spin delocalization in iron verdazyl complexes

et al. 2018

The verdazyl 'pincer' ligand, 1-isopropyl-3,5-dipyridyl-6-oxoverdazyl (dipyvd), coordinates iron to form a series of pseudooctahedral coordination compounds [Fe(dipyvd)2]n+ (n = 0-3). In the case where n = 2, the molecular geometry and physical and spectral properties are consistent with a low spin (S = 0) iron(ii) ion coordinated by two ferromagnetically coupled radical ligands. Upon one electron reduction, the room temperature effective magnetic moment of the complex jumps from μeff = 2.64 to μeff = 5.86 as a result of spin crossover of the iron atom combined with very strong ferromagnetic coupling of the remaining ligand centered unpaired electron with the metal center. The sign of the exchange is opposite to that observed in other high spin iron/radical ligand systems and appears to be a result of delocalization of the ligand unpaired electron across the whole molecule. The large change in magnetic properties, combined with a delocalized electronic structure and accessible redox potentials, suggests the utility of this and related systems in the development of novel molecular spintronic devices.

In this contribution, hydrophobic association and metal‐ligand coordination have been employed in a dual physical crosslinking strategy to access hydrogels based on micellar copolymerization of acrylamide and a hydrophobic acrylic monomer (containing terpyridine (terpy) for metal‐ligand interaction). The mechanical properties of these hydrogels are strongly influenced by the thermodynamic stability and kinetic lability of the metal‐terpy crosslinks present in these materials. While the hydrogel tensile strength and stability on water exposure are enhanced by choosing stronger Fe2+‐terpy crosslinks, the weaker and more kinetically labile Zn2+‐terpy coordination bonds enable significantly higher energy dissipation under tensile loading and self‐healing in the resultant hydrogels.
