Bridging ligands comprising two or more di-2-pyridylmethyl or amine arms: Alternatives to 2,2′-bipyridyl-containing bridging ligands

Ruthenium complexes of hexakis(cyanophenyl)[3]radialenes and their di(cyanophenyl)methane precursors: synthesis, photophysical, and electrochemical properties

“…For the meta isomer 3 it is possible that coordination of the bulky ruthenium species is causing a structural distortion or a reduction in conjugation for the ligand structure and hence the blue shift. In terms of electrochemical potentials of the Ru(PPh 3 ) 2 Cp and Ru(dppe)Cp* centres in dinuclear complexes 6, 7, 10 and 11, the diarylmethane ligands 4 and 5 have almost no effect on the redox properties of the metals which display similar oxidation potentials to [Ru(NCPh)(PPh 3 ) 2 Cp]PF 6 and [Ru(NCPh)(dppe)Cp*]PF 6 and only one oxidation wave.…”

“…The structures of (a) [3]-radialene, (b) hexa(2-pyridyl) [3]radialene (1); (c) hexakis(4-cyanophenyl) [3]radialene (2) and hexakis(3-cyanophenyl) [3]radialene (3); and (d)…”

“…Ruthenium(II) complexes of polypyridyl ligands with the ability to bridge multiple metals have been extensively studied [1,2], for example in the context of light harvesting antennae [3], to study electron transfer processes [4,5] and for molecular electronics [6,7].…”

Synthesis, Characterization and Coordination Chemistry of N,N'-bis(3-pyridylmethyl)benzene-1,4-dicarboxamide with Palladium and Ruthenium Salts

“…It has also been reported that N-H bonding donor group can act as an effective neutral anion receptor because it ability to bind anion via its hydrogen bond. Ligand contains nitrogen as a donor atom was also reported stable, convenient to synthesis and has unique properties useful in many applications [3][4][5][6]. Amide ligand is versatile ligand because its bombastic structure can act as good anion receptor and also form metallosupramolecule when it interacts with metal centre.…”

Synthesis and Coordination Chemistry of 2-(Di-2-pyridylamino)pyrimidine; Structural Aspects of Spin Crossover in an FeII Complex

“…Bridging ligands possessing 2,2'-bipyridine (bpy) and 1,10-phenanthroline units (phen), [12] di-2-pyridylmethane (dpm), [13,14] and di-2-pyridylamine (dpa) [13] chelating motifs, Figure 1(a), for facilitating strong metal-metal interactions within multinuclear complexes have been studied. In the context of systems for spin crossover, the use of di-2-pyridylamine as a chelating motif has attracted considerable attention.…”
