Abstract: In the title compound, C₉H₁₁NO·0.5H₂O, the asymmetric unit contains two similar molecules of 5,6,7,8-tetrahydroquinoline 1-oxide and one water molecule. The water molecule links the two O atoms of both independent N-oxides into dimers via O-HO hydrogen bonds, forming a three-dimensional network along [101], which is additionally stabilized by weak C-HO intermolecular interactions. In each molecule, the saturated six-membered rings exist in a conformation intermediate between a half-chair and sofa.
