Abstract :
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.
