【 摘 要 】

In the title compound, also known as 3,5-lutidine N-oxide dihydrate, C7H9NO·2H2O, the N—O bond is weakened due to the involvement of the O atom as an acceptor of hydrogen bonds from the two water molecules of crystallization present in the asymmetric unit. Fused R35(10) ring motifs based on O—H...O hydrogen bonds form chains in the [010] direction, which are further connected by weak C—H...O intermolecular contacts. As a result, the lutidine molecules are stacked in an efficient manner, with π–π contacts characterized by a short separation of 3.569 (1) Å between the benzene rings.
