【 摘 要 】

In the title hydrate, C16H23BrN2O·2H2O, the organic mol­ecule features a strong intra­molecular O—H⋯N hydrogen bond. The piperidine ring, in addition, adopts a chair conformation with the exocyclic C—N bond in an equatorial orientation. The water molecules of crystallization are disordered (each over two sets of sites with half occupancy.In the crystal, they associate into corrugated (100) sheets of (H2O)4 tetra­mers linked byO—H⋯O hydrogen bonds. The organic mol­ecules, in turn, are arranged at both sides of these sheets, linked by water–piperidine O—H⋯N hydrogen bonds.
