Abstract

The title compound, 2C16H27NO·H2O, crystallizes in the monoclinic P21/c space group with two independent mol-ecules (A and B) in the asymmetric unit. In the crystal, mol-ecules A and B are linked through the water mol-ecules by inter-molecular O-H⋯O and O-H⋯N hydrogen bonds, producing chains along the b-axis direction. These chains are linked with neighboring chains parallel to the (103) plane via C-H⋯π inter-actions, generating ribbons along the b-axis direction. The stability of the mol-ecular packaging is ensured by van der Waals inter-actions between the ribbons. According to the Hirshfeld surface study, H⋯H inter-actions are the most significant contributors to the crystal packing (80.3% for mol-ecule A and 84.8% for mol-ecule B).
