Abstract
The syntheses of four supramolecular reagents (SRs) based on (N-pyridylmethylene)aminobenzamides are reported. The crystal structure of 4′-(N-4-pyridylmethylene) aminobenzamide is dominated by an amide-py N–H…N hydrogen bond and an amide–carbonyl N–H…O hydrogen bond. The crystal structure of 4′-(N-3-pyridylmethylene)aminobenzamide contains the same N–H…N interaction but this time it is accompanied by an amide-imine N–H…N hydrogen bond. Finally, the crystal structure of 3′-(N-3-pyridylmethylene) aminobenzamide contains a well-known amide-amide ribbon constructed from two inequivalent N–H…O hydrogen bonds. The hydrogen-bond interactions in these three similar compounds are very different which indicates a structural flexibility that may be beneficial for successful co-crystallization reactions.
