| Abstract: | Molecules of the title compound, C10H7ClO, (I), are connected by a single strong O—H...O hydrogen bond into a simple C(2) chain, which runs parallel to the c axis and is additionally stabilized by intermolecular π–π stacking interactions. The significance of this study lies in the comparison drawn between the crystal structure of (I) and those of several of its simple analogues. This comparison shows a close similarity in the packing of the molecules that form π‐stacks along the shortest crystallographic axes. A substantial spatial overlap is observed between adjacent molecules in such a π‐stack, depending mainly on the kind of substituent. |
