Deskripsi
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 by O—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.
