N,N-Dimethyl-1H-pyrazolo­[3,4-d]pyrimidin-4-amine monohydrate

The asymmetric unit of the title compound, C7H9N5·H2O, consists of two formula units differing slightly in the orientation of the di­methyl­amino groups. In the crystal, a combination of O—H⋯N and N—H⋯O hydrogen bonds involving the water molecules of crystallization, as well as slipped π-stacking inter­actions between pyrazolo­pyrimidine units form layers parallel to the bc plane.
