1‐(Quinolin‐2‐yl)ethanone

The title compound, C11H9NO, crystallizes with four independent molecules in the asymmetric unit. The formyl group in each molecule is coplanar with the attached quinoline ring system. The independent molecules exist as two pseudo-inversion-related pairs. Each set of these molecules forms sheets parallel to the ac plane which are alternately stacked along the b axis. The crystal packing is stabilized by C-H center dot center dot center dot O intermolecular hydrogen-bonding interactions.
