(E)-1-(4-Amino-phen-yl)-3-[4-(benz-yl-oxy)phen-yl]prop-2-en-1-one

摘要

The title compound, C22H19NO2, crystallizes with two independent mol-ecules (A?and?B) in the asymmetric unit. The benz-yloxy ring in mol-ecule?A?is disordered over two sets of sites, with a refined occupancy ratio of 0.665?(6):0.335?(6). Both mol-ecules have an?E?conformation about the C=C bond of the prop-2-en-1-one unit. In the major component of mol-ecule?A, the amino-benzene and benz-yloxy rings are inclined to the central benzene ring by 20.12?(16) and 36.2?(3)°, respectively, and by 55.6?(3)° to one another. In mol-ecule?B, the corresponding dihedral angles are 23.65?(12), 10.24?(14) and 23.07?(14)°, respectively. In the crystal, the two mol-ecules are linked by an N—H?O hydrogen bond. These?A–B?units are linked by N—H?π?and C—H?π?inter-actions, forming undulating sheets parallel to the?ab?plane.
