Rocco, Dalila; Prescimone, Alessandro; Constable, Edwin C.; Housecroft, Catherine E. published the artcile< Switching conformation of 3,2':6',3''-tpy domains in 4'-(4-n-alkyloxyphenyl)-3,2':6',3''-terpyridines>, Recommanded Product: 1-(Pyridin-3-yl)ethanone, the main research area is terpyridine preparation crystal structure conformation; 3,2′:6′,3″-terpyridine; conformation; crystal structure; intermolecular interactions.
The preparation and characterization of 4′-(4-n-octyloxyphenyl)-3,2′:6′,3”-terpyridine (8) and 4′-(4-n-nonyloxyphenyl)-3,2′:6′,3”-terpyridine (9) are reported. The single crystal structures of 4′-(4-n-hexyloxyphenyl)-3,2′:6′,3”-terpyridine (6), 4′-(4-n-heptyloxyphenyl)-3,2′:6′,3”-terpyridine (7), and compounds 8 and 9 have been determined The conformation of the 3,2′:6′,3”-tpy unit is trans,trans in 6 and 7, but switches to cis,trans in 8 and 9. This is associated with significant changes in the packing interactions with a more dominant role for van der Waals interactions between adjacent n-alkyloxy chains and C-Hmethylene··· π interactions in 8 and 9. The solid-state structures of 6 and 7 with the n-hexyloxy and n-heptyloxy chains feature interwoven sheets of supramol. assemblies of mols., with pairs of n-alkyloxy chains threaded through cavities in an adjacent sheet.
Molecules published new progress about Conformation. 350-03-8 belongs to class pyridine-derivatives, and the molecular formula is C7H7NO, Recommanded Product: 1-(Pyridin-3-yl)ethanone.
