چکیده
The organic mol-ecule of the title monohydrate, C(12)H(9)IN(2)O(3)·H(2)O, features a disordered furyl ring with the major component [site occupancy = 0.575 (18)] having the carbonyl O and furyl O atoms syn, and the other conformation having these atoms anti. The mol-ecule is slightly twisted with the dihedral angle between the benzene and furyl rings being 10.3 (6)° (major component). An intra-molecular O-H⋯N(imine) hydrogen bond is formed. In the crystal, the water mol-ecule accepts a hydrogen bond from an amine H atom, and forms two O-H⋯O(carbon-yl) hydrogen bonds, thereby linking three different carbohydrazide mol-ecules. The result is a supra-molecular layer parallel to (001). The closest contacts between layers are of the type I⋯I, at a distance of 3.6986 (6) Å.
