The structure of 1,1′-(2,6-pyridindiyl)bis[6,7-dihydro-4-(4-methoxyphenyl)-5H-cyclopenta[c]pyridine

Abstract

1,1'-(2,6-Pyridinediyl)bis[6,7-dihydro-4-(4-methoxyphenyl)-5H-cyclopenta[c]pyridine was obtained in good yield (52%) by reacting 3,3'-(2,6-pyridinediyl)bis[6-(4-methoxyphenyl)-1,2,4-triazine] with 1-morpholincyclopene during its solvent-free fusion at 200 °C, i.e., the PASE approach was implemented in contrast to the previously proposed boiling in 1,4-dioxane in the literature. The structure of the obtained compound was studied in detail using X-ray structure analysis of its single crystal, and a comparison was made with information previously described in the literature (in particular, the bond lengths between atoms and the valence angles, as well as the mutual arrangement of aromatic fragments). The features of the supramolecular structure of the obtained compound that had not been described previously were characterized, including the arrangement of two monomers stacked head-to-head, which ensured the minimal distance between adjacent structures.
