چکیده
In the title compound, C(11)H(14)ClNO, the piperidine ring adopts a chair conformation: the hydroxyl substituent and the N-bound H atom occupy the axial positions, while the benzene ring occupies the equatorial position. In the crystal, the mol-ecules are linked into a centrosymmetric tetra-mer through strong O-H⋯N and weak N-H⋯O hydrogen bonds; the N and O atoms act as both donor and acceptor for these inter-actions. The tetra-mers are further joined by hydrogen bonds into a layer parallel to (100).
