The solvent effect on the title compound was studied by examining changes in the positions of IR bands belonging to the NH and CO bonds and in the dipole moments in benzene and dioxane solutions. The results are discussed in terms of intramolecular hydrogen bonding and spatial arrangement of the CONHCSNH grouping.

The title compound (systematic name: 3-chloro-5-fluoro-2-hydroxybenzaldehyde), C7H4ClFO2, is a dihalogenated salicylaldehyde derivative that has been studied for its antibacterial characteristics. The salicylaldehyde engages in intramolecular hydrogen bonding with an O—H...O distance of 2.6231 (19) Å while the molecules pack together via weak intermolecular C—H...O, C—H...F and F...O interactions and offset face-to-face π-stacking.

Intramolecular Hydrogen

Infrared spectra of various aromatic-substituted oxalamidines have been obtained. The behavior of the vibrational bands originating in the amidine groupings as a function of solution concentration is interpreted as indicating the presence of persistent intramolecular hydrogen bonding.

Certain unusual features in the infrared spectra of o-nitrobenzaldehyde have been interpreted either in terms of an intramolecular hydrogen bond or in terms of steric interactions. As an extension of these studies we have investigated the ultraviolet, infrared, and n.m.r. spectra of o-nitrobenzaldehyde and of suitable reference compounds and have re-examined the available other evidence. It is concluded that the observed spectral changes can best be explained in terms of steric interactions rather than in terms of intramolecular hydrogen bonding.
