Crystal structure of ethyl (E)-4-(4-chlorophen­yl)-4-meth­oxy-2-oxobut-3-enoate

In the title compound, C₁₃H₁₃ClO₄, the dihedral angle between the chloro­benezene ring and the least-squares plane through the 4-meth­oxy-2-oxobut-3-enoate ethyl ester residue (r.m.s. deviation = 0.0975 Å) is 54.10 (5)°. In the crystal, mol­ecules are connected by meth­oxy–ketone and benzene–carboxyl­ate carbonyl C—H...O inter­actions, generating a supra­molecular layer in the ac plane.
