摘要

The title compound, C22H16N2O2 {systematic name: 3-(4-hy-droxy-phen-yl)-2-[(E)-2-phenyl-ethen-yl]quinazolin-4(3H)-one}, consists of a substituted 2-[(E)-2-aryl-ethen-yl]-3-aryl-quinazolin-4(3H)-one skeleton. The substituents at the ethyl-ene fragment are located in trans positions. The phenyl ring is inclined to the quinazolone ring by 26.44?(19)°, while the 4-hy-droxy-phenyl ring is inclined to the quinazolone ring by 81.25?(8)°. The phenyl ring and the 4-hy-droxy-phenyl ring are inclined to one another by 78.28?(2)°. In the crystal, mol-ecules are connected via O—H?O hydrogen bonds, forming a helix along the a-axis direction. The helices are linked by C—H?π inter-actions, forming slabs parallel to (001).
