چکیده
In the title mol-ecule, C(8)H(8)IN(3)O(2), there is an intra-molecular O-H⋯N hydrogen bond between the hy-droxy group and the imine N atom, which generates an S(6) ring. In the crystal, the carbonyl O atom accepts two different N-H⋯O hydrogen bonds, which connect mol-ecules with two R(2) (2)(8) motifs.

The title compound, C(16)H(17)N(3)O(3)·H(2)O, exists in the E conformation with respect to the azomethine C=N double bond. While the phenyl ring is almost coplanar with the central hydrazinecarboxamide group [dihedral angle = 14.18 (11)°], it is twisted slightly with respect to the other aromatic ring in the mol-ecule, with a dihedral angle of 22.88 (13)°. The packing is dominated by O-H⋯O, N-H...

The asymmetric unit of the title compound, C(9)H(11)N(3)O(3), consists of two crystallographically independent mol-ecules. Both mol-ecules are almost planar, with r.m.s. deviations of 0.107 and 0.099 Å. In the crystal, the two independent mol-ecules form a dimer with an R(2) (2)(8) ring motif via N-H⋯O hydrogen bonds. The dimers are further linked into a three-dimensional network by O-H⋯O and N...
