In the title compound, C~15~H~15~N~3~O~4~·H~2~O, the organic molecule exists in the keto–imine tautomeric form. The benzene ring makes a dihedral angle of 49.9 (2)° with the pyridine ring. The molecules pack in a three-dimensional framework structure by a combination of O—H...O, O—H...N, N—H...O and
The asymmetric unit of the title compound, C 14 H 13 N 3 O 3 ÁH 2 O, consists of one isonicotinic acid (3-hydroxy-4-methoxybenzylidene)hydrazide (IBH) molecule and one water molecule connected through an O-HÁ Á ÁO hydrogen bond. Further O-HÁ Á ÁO, O-HÁ Á ÁN and N-HÁ Á ÁO hydrogen bonds result in the
