(2E,6E)-2,6-Bis(4-ethoxybenzylidene)cyclohexanone

The title compound, C24H26O3, was prepared by the condensation reaction of 4-ethoxybenzaldehyde with cyclohexanone. The molecule has crystallographic mirror symmetry and exhibits a butterfly-shaped geometry, with a dihedral angle of 5.46 (1)° between the two benzene rings. Weak intermolecular C—H...π interactions help stabilize the crystal structure.
