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

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)°. In the crystal, O—H⋯N hydrogen bonds and weak π-stacking inter­actions form inversion dimers, which are linked into chains extending along the c-axis direction by two sets of N—H⋯O hydrogen bonds. The chains are connected into layers parallel to the bc plane by two sets of C—H⋯π(ring) inter­actions.
