[Ru(3-pyridyl-4′-terpy)2]2+ as a metallo-ligand – Adding to the complexity of supramolecular polymers

A Journey from Supramolecular Chemistry to Nanoscale Networks

“…In practice, a much more complex structure is obtained with a two-dimensional {6,3} net containing both linear two-coordinate and trigonal three-coordinate silver centres. [30] The 'simple' unit in the {6,3} net comprises eight {Ru(2} 2 } expanded ligands linked by two two-coordinate silver centres (pale green) and the six three-connected silver nodes (pink) as presented in Fig. 8b.…”

Self-Assembly with 2,6-Bis(1-(pyridin-4-ylmethyl)-1H-1,2,3-triazol-4-yl)pyridine: Silver(I) and Iron(II) Complexes

“…In particular, classical 2,2-bipyridine (bipy) and 2,2′:6′,2″-terpyridine (terpy) chelators conjugated to pyridyl units have received considerable attention ( Figure 1 A–D). The chelate effect leads to the initial complexation of a metal ion within the bidentate or tridentate pocket of the ligands, while the addition of a second equivalent of the same or a different metal ion generates either discrete [ 18 , 19 , 20 , 21 ] or polymeric [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ] metallosupramolecular assemblies.…”

The relevance of the fluorine interactions in the supramolecular structure of a complex constructed from copper(II) hexafluoroacetylacetonate and the 4′-(3-pyridyl)-2,2′:6′,2″-terpyridine ligand. Novel C–F/π synthons involving the π-system of the terpyridine moieties and those of the hexafluoroacetylacetonate chelate rings

“…The incorporation of new functional ligands such as 2,2 0 :6 0 ,2 00 -terpyridine (terpy) and its derivatives into supramolecular assemblies by transition metal complexation, creating novel materials with useful chemical and physical properties, appears as one important challenge in this field [1,2]. In this sense, the pyridyl-substituted ligands 4 0 -(n-pyridyl)-terpyridine (n = 2, 3 or 4) have been studied and found that they can act as bridging N-donor ligands using its tridentate terpyridyl fragment and the monodentate n-pyridyl moiety [3][4][5][6][7][8][9][10][11]. In particular, only recently, the bridging mono-tridentate capacity of the 4 0 -(3-pyridyl)-2,2 0 :6 0 ,2 00 -terpyridine (pyterpy, Scheme 1) ligand has been tested.…”

“…In particular, only recently, the bridging mono-tridentate capacity of the 4 0 -(3-pyridyl)-2,2 0 :6 0 ,2 00 -terpyridine (pyterpy, Scheme 1) ligand has been tested. More specifically, the reported examples showing this capacity appear in homometallic polymers [3][4][5], heterobimetallic polymers [6,7] and trinuclear heterobimetallic species [6]. Besides, solid state studies show that a significant group presenting weak intermolecular interactions is the one involving the pyterpy ligand in a p-p stacking between neighboring pyridyl rings [4,6].…”
