Synthesis, crystal structure and Hirshfeld surface analysis of 2-[(4-hydroxyphenyl)amino]-5,5-diphenyl-1H-imidazol-4(5H)-one

In the title molecule, C21H17N3O2, the five-membered ring is slightly ruffled and dihedral angles between the pendant six-membered rings and the central, five-membered ring vary between 50.78   (4) and 86.78   (10) ° . The exocyclic nitrogen lone pair is involved in conjugated π bonding to the five-membered ring. In the crystal, a layered structure is generated by O — H...N and N — H...O hydrogen bonds plus C — H... π (ring) and weak π -stacking interactions.
