The title compound, C10H14O, adopts a conformation typical of cis-1,3-disubstituted cyclobutanes, with the ring flexed out of planarity so that the substituents are maximally separated. The two intermolecular C—H...O=C close contacts found include

The title racemate, C13H19NO2, is a pre-dehydration intermediate isolated from the base-catalysed Robinson annulation of (+/−)-2-(2-cyanoethyl)cyclohexanone. Centrosymmetric dimers are formed by reciprocal hydroxyl-to-ketone hydrogen bondin

The title compound, C6H8O3, is the smallest keto acid yet found to aggregate in the solid as acid-to-ketone hydrogen-bonded catemers. Four translational chains pass through the cell in the a direction [O...O = 2.6915 (14) A and O-H...O = 166 degrees]

The title racemate (C11H14O3) aggregates in the solid as acid-to-ketone hydrogen-bonding catemers [O⋯O = 2.6557 (13) A and O—H⋯O = 170°], whose components are glide-related. The stereochemistry of the carboxyl group arises spontaneously during

The title compound, C9H8O3, adopts a conformation in which both substituents lie nearly coplanar with the ring. Asymmetric units aggregate by centrosymmetric carboxyl pairing. Close offset stacking of rings in parallel planes creates intermolecular

The title racemate, C12H16O3, aggregates in the solid state as translational acid-to-ketone hydrogen-bonded catemers. The stereochemistry of the side chain relative to the ring junction arises spontaneously during the synthesis. The four hydrogen-bon
