title: Hydrogen bonding and ring asymmetry in (+/-)-cis-2-phenylcyclopropanecarboxylic acid.
abstract: The title compound, (+/-)-cis-2-phenylcyclopropanecarboxylic acid, C10H10O2, crystallized in the centrosymmetric space group P2(1)/n. The hydrogen bonding is of the cyclic dimer type about a center of symmetry; the Odonor...Oacceptor distance is 2.645 (2) A. The carboxylic H atom is ordered, as are the O atoms. The cyclopropane ring is asymmetric; the values found for the asymmetry parameters are delta(COOH) = -0.045 (4) A and delta(phenyl) = -0.027 (4) A.
