“…The molecule is significantly planar, as reflected in the values determined for the torsion angles. This is also true for molecules substituted with methoxy and/or hydroxy groups at different points of both phenyl sub-systems (Fronczek et al, 1987;Wallet et al, 1995;Subbiah Pandi et al, 2003;Chu et al, 2004;Wafo et al, 2005;Radha Krishna et al, 2005;Wu et al, 2005;Usman et al, 2006).…”

Key indicators: single-crystal X-ray study; T = 150 K; mean (C-C) = 0.004 Å; R factor = 0.064; wR factor = 0.139; data-to-parameter ratio = 12.8.The molecular conformation of the title compound, C 18 H 18 O 5 , is stabilized by a strong intramolecular hydrogen bond between the hydroxyl and carbonyl groups. The C C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1) .
