Abstract: The title compound, C₃₂H₂₈N₂O, is a flexible Schiff base displaying a trans configuration across the C=N double bond. It was prepared in high yield by condensation of -methylcinnamaldehyde and bis(4-aminophenyl) ether in methanol at room temperature. The sample, with pseudo-orthorhombic cell parameters, exhibited merohedral twinning by rotation 180° around a*, with a refined twin domain fraction of 0.722 (1). The elongated shape of the elementary cell corresponds to the shape and direction of the molecules. The dihedral angle between the O-linked aromatic rings is 57.86 (8)°.
