Abstract: In the title compound, C12H11N3O3·2H2O, the dihedral angle formed by the planes of the pyridine and the furan rings of the organic carbohydrazide mol­ecule is 4.66 (7)°. In the crystal, these mol­ecules form stacks along the b-axis direction, neighbouring mol­ecules within each stack being related by inversion and the shortest distance between the centroids of the pyridine and furan rings being 3.714 (1) Å. Mol­ecules from neighboring stacks are linked by pairs of N-H...O hydrogen bonds. The water mol­ecules fill the channels between the stacks being linked by O-H...O hydrogen bonds into helices along [010]. Besides this, water mol­ecules are involved in O-H...N and O-H...O hydrogen bonds with the carbohydrazide mol­ecules, thus forming a three-dimensional network, augmented by weak C-H...O interactions.
