title: 4-[(2-Hydr-oxy-1-naphth-yl)(piperidin-1-yl)meth-yl]benzonitrile.
abstract: In the title compound, C(23)H(22)N(2)O, obtained from the condensation reaction of 4-formyl-benzonitrile, 2-naphthol and piperidine, the dihedral angle between the naphthalene ring system and the benzene ring is 75.31 (4)°. The piperidine ring adopts a chair conformation. The crystal structure is stabilized by inter-molecular C-H⋯N hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. An intra-molecular O-H⋯N hydrogen bond is also present.
