title: Crystal structure of 2,6-dimethyl-4-pyridone hemihydrate.
abstract: The title compound (systematic name: 2,6-dimethyl-1H-pyridin-4-one hemihydrate), C7H9NO·0.5H2O, has a single planar mol-ecule in the asymmetric unit with the non-H atoms possessing a mean deviation from planarity of 0.021 Å. There is also half of a water mol-ecule present in the asymmetric unit. In the crystal, infinite (001) sheets are formed by N-H⋯O and O-H⋯O hydrogen bonds.
