title: 3-Benzyl-3-hy-droxy-2-phenyl-3H-indole 1-oxide.
abstract: The asymmetric unit of the title compound, C(21)H(17)NO(2), contains two crystallographically independent mol-ecules of similar geometry. The indole ring systems form dihedral angles of 8.30 (5) and 9.58 (5)° with the attached phenyl rings, and 56.96 (5) and 57.68 (5)° with the aromatic rings of the respective benzyl groups. The mol-ecular conformations are stabilized by intra-molecular C-H⋯O hydrogen bonds. In the crystal structure, centrosymmetrically related pairs of mol-ecules are linked into dimers through pairs of inter-molecular O-H⋯O hydrogen bonds, generating 12-membered rings with R(2) (2)(12) motifs. The dimers are further linked into a three-dimensional network by C-H⋯O inter-actions.
