✦ Synopsis

The title compound, C 11 H 12 O 3 , was synthesized from 4hydroxy-3-methoxybenzaldehyde and acetone. The molecule has a high degree of conjugation throughout the system and intermolecular hydrogen bonds connect adjacent molecules to form one-dimensional chains.

H atoms were positioned geometrically [C-H distances of 0.93 (Csp 2 -H) and 0.96 A ˚(methyl), and O-H = 0.82 A ˚]. U iso (H) values were set equal to xU eq (carrier atom), where x = 1.2 for CH and 1.5 for O and methyl C.
