Bis[4-(2-benzyl-idenepropyl-idene-amino)phen-yl] ether.

The title compound, C(32)H(28)N(2)O, is a flexible Schiff base displaying a trans configuration across the C=N double bond. It was prepared in high yield by condensation of α-methyl-cinnamaldehyde and bis-(4-amino-phen-yl) ether in methanol at room temperature. The sample, with pseudo-ortho-rhom-bic 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 mol-ecules. The dihedral angle between the O-linked aromatic rings is 57.86†(8)°.
