Crystallographic and spectroscopic characterization of 2-bromo-p-tolu-aldehyde.

The title compound (systematic name: 2-bromo-4-methyl-benzaldehyde), C8H7BrO, is a halogenated benzaldehyde derivative. The mol-ecule contains an aldehyde moiety, ortho bromine, and para methyl group. Packing via van der Waals forces, the mol-ecules are arranged with both offset face-to-face and an edge-to-face π-stacking inter-action revealed by Hirshfeld surface characterization.
