Three versatile 4′-substituted 2,2′:6′,2”-terpyridine compounds (1-3) having different substitutions (4-ethoxyphenyl, 4-methoxyphenyl and pyridyl) at 4′-position of the central pyridine ring have been synthesized and structurally characterized. Three representative crystal structures have been determined through single crystal X-ray diffraction anal. X-ray crystallog. revels that the structures are stabilized through C-H···π and π-π stacking interactions. In the solid-state, the supramol. assemblies of the title compounds have been explored in detail. Compounds (1) and (3) exhibits both C-H···π and π-π interactions in building supramol. assemblies whereas compound (2) exhibit π-π interaction only. All the intermol. interactions that are involved within the structures are quantified through Hirshfeld surface analyses. The weak noncovalent interactions that played significant role in building supramol. assemblies are further characterized by Bader’s theory of ‘atoms-in-mols.’ (AIM). Finally, the supramol. networks are characterized by theor. ‘Noncovalent Interaction’ (NCI) plot index. The supramol. solid-state frameworks of three 4′-functionalized 2,2′:6′,2”-terpyridine derivatives have been quantified which are further characterized theor. by the Bader’s theory of ‘atoms-in-mols.'(AIM) and ‘noncovalent interaction’ (NCI) plot index. In the part of experimental materials, we found many familiar compounds, such as 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3Synthetic Route of C20H14N4)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Synthetic Route of C20H14N4 Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
