(E)-3-{4-[(7-Chloro­quinolin-4-yl)­oxy]-3-meth­oxy­phenyl}-1-(4-methyl­phenyl)prop-2-en-1-one: a ladder-like structure resulting solely from [pi]-[pi] stacking inter­actions

In the title compound, C₂₆H₂₀ClNO₃, the quinoline fragment is nearly orthogonal to the adjacent aryl ring, while the rest of the mol­ecular skeleton is close to being planar. The crystal structure contains no hydrogen bonds of any sort, but there are two [pi]-[pi] stacking inter­actions present. One, involving the quinoline ring, links mol­ecules related by inversion, while the other, involving the two nonfused aryl rings, links mol­ecules related by translation, so together forming a ladder-type arrangement
