Crystallographic and spectroscopic characterization of 3-chloro-5-fluoro­salicyl­aldehyde

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.
