Crystal structure and Hirshfeld surface analysis of 1-(-butyl-amino)-3-mesitylpropan-2-ol hemi-hydrate.

The title compound, 2CHNO·HO, crystallizes in the monoclinic 2/ space group with two independent mol-ecules ( and ) in the asymmetric unit. In the crystal, mol-ecules and are linked through the water mol-ecules by inter-molecular O-H⋯O and O-H⋯N hydrogen bonds, producing chains along the -axis direction. These chains are linked with neighboring chains parallel to the (103) plane C-H⋯π inter-actions, generating ribbons along the -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 and 84.8% for mol-ecule ).
