Abstract:
The crystal of ethyl 3-hy-droxy-benzoate, C9H10O3, comprises two independent mol-ecules in the asymmetric unit. Each mol-ecule is approximately planar with the ethyl group directed away from the carbonyl-O atom. The planarity is reflected in the phenyl-C-C-O-C(methyl-ene) torsion angles of -179.40 (10) and 177.88 (11)°, respectively. The greatest difference between the mol-ecules is found in the relative orientations of the methyl groups as seen in the carboxyl-ate-C-O-C-C(meth-yl) torsion angles of -178.76 (11) and -171.12 (13)°, respectively. In the crystal, hydroxyl-O-H⋯O(carbon-yl) hydrogen-bonding occurs within almost planar chains along [100].
