(E)-3-[4-(Hexyloxy)phenyl]-1-(4-hydroxyphenyl)prop-2-en-1-one

Abstract

In the title compound, C21H24O3, the enone group adopts an s–cis conformation. The planes of the aromatic rings are inclined at an angle of 6.1 (1)°. The alk­oxy tail is not linear, with the maximum deviation from the least-squares plane being 0.375 (2) Å. Mol­ecules are connected into extended chains along the a axis through O—H⋯Ocarbon­yl hydrogen bonds and are inter­linked via C—H⋯O inter­actions to form a two-dimensional array parallel to the ab plane.

“…angle to 125.18 (9)° may be the result of a close H14A and H16B (2.37 Å) contact. The geometric parameters are consistent to those observed in closely related structures (Razak et al, 2009;Ngaini et al, 2010;Ngaini et al, 2011).…”
