“…Indeed, at the turn of the millennium, 2,2′-bipyridine was described as “the most widely used ligand” [1] a status that has changed little in the intervening two decades. Not surprisingly, this commonly used type of ligand, together with the higher oligopyridines and the closely related species 1,10-phenanthroline, 2 (Figure 1), has been the subject of a number of reviews [2,3,4,5,6,7,8] since the first review of their coordination chemistry in 1954 [9]. 2,2′-Bipyridine is the first member of a series of higher oligopyridines, which can also act as polydentate ligands for metal-centres [10,11,12,13,14,15].…”

The first fifty years of the chemistry of 2,2′-bipyridine are reviewed from its first discovery in 1888 to the outbreak of the second global conflict in 1939. The coordination chemistry and analytical applications are described and placed in the context of the increasingly sophisticated methods of characterization which became available to the chemist in this time period. Many of the “simple” complexes of 2,2′-bipyridine reported in the early literature have been subsequently shown to have more complex structures.

“…As for both of 1a, b, strong p-p n absorptions for the coordinating ligand were observed in 250-350 nm region. Most notably, both of 1a, b exhibited broad absorption bands in the 500-900 nm region, which were assigned to metal-to-ligand charge transfer (MLCT) transitions that are characteristic of Ru(II)-polypyridyl complexes [21,22]. These absorption peaks were extended into a longer-wavelength region up to 900 nm, though their absorption maxima were blue-shifted compared with that of black dye.…”

“…Fe charge-transfer transition) at λ = 356 nm and two additional bands at 223 and 266 nm attributable to the aromatic ligand. In Fe 2+ phen spectrum, the band at λ = 356 nm is replaced by a band with a maximum at λ = 510 nm (attributable to a d→π* metal to ligand charge transfer transition) and two shoulders at λ = 455 and 493 nm [34]. The signals observed at about 356 and 510 nm will therefore be indicative of the presence of a phenanthroline complex of Fe 3+ and Fe 2+ , respectively.…”

The interaction of volatile organic sulfur derivatives, such as 1-heptanethiol (C 7 H 16 S), with clay minerals treated with a μ-oxo Fe 3+-phenanthroline 1:1 complex results strongly affected by crystal chemical properties of pristine mineral phases. In particular, two sepiolite clays with different structural features demonstrated significantly different ability to immobilize the Fe 3+-phenanthroline complex at two pH values (pH = 5.4 and pH = 2.3). The most effective binding was obtained with sepiolite with higher structural disorder at pH 5.4. Accordingly, the resulting hybrid material showed also the greatest efficiency in removal of thiol in gas phase. A direct correlation can be established between the adsorption of the Fe 3+-phenanthroline complex and the gas binding process at room temperature. In fact, 1-heptanethiol entrapping occurs via redox reactions between Fe 3+ and a first thiol molecule to give the reduced Fe 2+-phenanthroline complex and disulfide, followed by the binding of further thiols to the reduced metal centre. The extremely high amount of thiol immobilized by the hybrid material also suggests the co-presence of a catalytic mechanism that guarantees the reoxidation of Fe +2 to Fe +3 and the restoration of redox reactions with thiol. Investigation and conclusions were supported by the several experimental techniques: elemental analysis, X-ray powder diffraction analyses, UV-Vis measurements, FT-IR and NMR spectroscopies, thermogravimetric analyses.
