(E)-3-[4-(Pent­yloxy)phen­yl]-1-phenyl­prop-2-en-1-one

The title compound, C20H22O2, crystallizes with two independent mol­ecules in the asymmetric unit. In each mol­ecule, all the non-H atoms lie in a common plane (r.m.s. deviations of 0.098 and 0.079 Å). There is a π–π stacking inter­action in the crystal structure. The central aromatic rings of the two mol­ecules, which are stacked head-to-tail one above the other, are separated by centroid-to-centroid distances of 3.872 (13) and 3.999 (10) Å
