1-Hydroxycyclobutane-1-carboxylic acid

R. Betz and P. Klüfers

Abstract: The title compound, C₅H₈O₃, was prepared as a potentially chelating molecule bearing the conformationally rigid cyclobutane group. The cyclobutane ring is arranged perpendicular to the carboxyl group. In the polar crystal structure, each molecule exhibits four hydrogen-bonded contacts to neighbouring molecules. Instead of the formation of typical carboxylic acid dimers, an infinite hydrogen-bonded chain with alternating O-H and O=C-O-H units is observed.
