o- and m-Benzenedicarbaldehyde

D. Britton

Abstract: o-Benzenedicarbaldehyde (systematic name: benzene-1,2-dicarbaldehyde), C₈H₆O₂, exhibits a weak intramolecular hydrogen bond between an aldehyde H atom and the O atom of the adjacent aldehyde group, with a CO distance of 2.852 (2) Å. m-Benzenedicarbaldehyde (systematic name: benzene-1,3-dicarbaldehyde), C₈H₆O₂, occurs as two different isomorphs. In all three crystals, there are intermolecular C-HO contacts involving both aldehyde and ring H atoms.

Formula: Two isomers of C₈H₆O₂
