Redetermination of 1-naphthaleneacetic acid

Z.-A. Li, D.-Y. Chen and L.-J. Liu

Abstract: The crystal structure of the title compound, C₁₂H₁₀O₂, was originally determined by Rajan [Acta Cryst. (1978). B34, 998-1000] using intensity data estimated from Weissenberg films. This redetermination provides a structure with significantly improved precision with respect to the geometric parameters. In the crystal structure, intermolecular O-HO hydrogen bonds, weak C-HO hydrogen bonds and C-H interactions link the molecules into a two-dimensional sheet lying parallel to (100).
