In the title compound, C14H17NO, the piperidine ring is in a half‐chair conformation. The mol­ecules are linked into C(7) chains by an inter­molecular C—H⋯O hydrogen bond.

An octadentate cyclen-based europium complex with amidic and hydroxyalkyl pendent moieties exhibits pH dependent ligand denticity associated with anion recognition. Unusually high hydration numbers are determined for ortho-phthalate ternary outer-sphere complexes for which modulation of lanthanide-based luminescence is observed.
