Crystal structure of 3-(4-hy­droxy­phen­yl)-2-[(E)-2-phenyl­ethen­yl]quinazolin-4(3H)-one

The title compound, C(22)H(16)N(2)O(2) {systematic name: 3-(4-hy­droxy­phen­yl)-2-[(E)-2-phenyl­ethen­yl]quinazolin-4(3H)-one}, consists of a substituted 2-[(E)-2-aryl­ethen­yl]-3-aryl­quinazolin-4(3H)-one skeleton. The substituents at the ethyl­ene fragment are located in trans positions. The phenyl ring is inclined to the quinazolone ring by 26.44 (19)°, while the 4-hy­droxy­phenyl ring is inclined to the quinazolone ring by 81.25 (8)°. The phenyl ring and the 4-hy­droxy­phenyl ring are inclined to one another by 78.28 (2)°. In the crystal, mol­ecules are connected via O—H⋯O hydrogen bonds, forming a helix along the a-axis direction. The helices are linked by C—H⋯π inter­actions, forming slabs parallel to (001).
