4,7-Dichlorotricyclo[3.1.1.03,6]heptane-2-carboxylic acid
Abstract
The structure of the carboxylic acid derivative of the new substituted open-cage system, 4,7-dichlorotricyclo[3.1.1.03,6]heptane-2-carboxylic acid, C8H8Cl2O2, shows that the carboxyl C atom has close contacts with C atoms of the cage system. Hydrogen bonds from the carboxylic acid functional groups of adjoining molecules form centrosymmetric dimers.
