The molecule of the title compound, C 9 H 9 Cl 2 NO 2 , is a zwitterion with cationic iminium and an anionic phenolate group, which form an intramolecular N-HÁ Á ÁO hydrogen bond closing a six-membered pseudocycle. Intermolecular O-HÁ Á ÁO hydrogen bonds link the molecules into infinite chains runni
The crystal structure of the title compound, C 16 H 17 NO 2 , contains two independent molecules in the asymmetric unit. Both molecules adopt the phenol-imine tautomeric form, with strong intramolecular O-HÁ Á ÁN hydrogen bonds. The crystal packing is stabilized by van der Waals interactions.
The title compound, C~15~H~15~NO~3~, derived from the condensation of dehydroacetic acid and __p__-toluidine, crystallizes in a zwitterionic form with cationic iminium and anionic enolate groups, which complete a six-membered pseudocycle __via__ an intramolecular N—H...O hydrogen bond. C—H...O inter
The title salt, C~8~H~20~NO~5~ ^+^·C~7~H~4~NO~4~ ^−^·H~2~O, is composed of a 4-nitrobenzoate anion, a [2-hydroxy-1,1-bis(hydroxymethyl)ethyl]bis(2-hydroxyethyl)ammonium (NBHHP) cation and a water molecule. The three units are linked by O—H...O hydrogen bonds.
