Abstract
In the title compound, C16H20O6, the conformation about the C=C double bond [1.344 (2) Å] is Z. With respect to this bond, the ketone is almost coplanar [C - C - C - O torsion angle = -179.60 (10)°] and the ester is almost perpendicular [C - C - C - O = 78.42 (13)°]. The methoxy substituents of the central benzene ring are either almost coplanar [C - C - O - C = 3.54 (15) and 177.70 (9)°] or perpendicular [C - C - O - C = 80.08 12)° for the central substituent]. In the crystal, the three-dimensional architecture features C - H⋯O and π-π [inter-centroid distance = 3.6283 (6) Å] interactions. © 2013 Zukerman-Schpector et al.
