摘要：
The two ester groups have different orientations, with C=C-C=O torsion angles of -165.7(3) and -89.4(4)degrees respectively for the groups remote from and adjacent to the Cl substituent. The remote ester group is therefore fully conjugated with the C=C double bond [cos2(angle) = 0.94] and the adjacent group nonconjugated [cos2(angle) = 0], presumably as a result of steric effects.
