Abstract

The mono‐arylic compound, methyl β‐orcinol‐carboxylate (I) is one of the principal components of lichens which grow on the oak tree. In the crystal structure of I the molecules are H‐bonded to form sheets separated by 3.56 (5) Å. The carbonyl O‐atom of the ester group and the ortho‐hydroxyl group form a strong intramolecular H‐bond. The IR. spectrum of the solid contains two (O‐‐H)‐stretching frequencies which, by comparison with the spectra of the 4‐methoxy and the 2‐methoxy analogues, can be assigned to one intra‐ and one intermolecular H‐bond.
