Structural Reporting :- 2,6-Bis(3,4-dimethoxybenzylidene)-4-ethylcyclohexanone

Abstract: In the title compound, C26H30O5, both the double bonds exist in an E configuration. The aryl rings are not coplanar with the adjacent olefinic groups owing to non-bonded interactions between the ortho H atoms of the aryl rings and the equatorial H atoms at the 3- and 5-positions of the cyclohexyl ring; the dihedral angles between the aryl rings and the olefinic groups are 33.7 (3) and 48.6 (4)°. The cyclohexanone ring adopts an envelope conformation and the crystal structure is stabilized by C-H...O hydrogen bonds.
