Abstract
In the title compound, C14H14ClNO4, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.0142 Å) and ester planes is 18.99 (3)°. The C-O-C-Cm (m = meth-yl) torsion angle is -172.08 (10)°, indicating a trans conformation. In the crystal, the mol-ecules are linked by C-H⋯O and C-H⋯N inter-actions, generating layers lying parallel to (101). Aromatic π-π stacking [centroid-centroid distances = 3.557 (2) and 3.703 (2)Å] links the layers into a three-dimensional network.
