چکیده
The asymmetric unit of the title compound, C(16)H(17)N(3)O(4)·2H(2)O, contains one Schiff base mol-ecule and two water mol-ecules. The Schiff base mol-ecule exists in an E configuration with respect to the C=N double bond and is essentially planar, the dihedral angle between the benzene and pyridine rings being 5.48 (8)°. The three meth-oxy groups are also coplanar with the benzene ring [C-O-C-C torsion angles = 3.9 (2), 178.51 (15) and 0.8 (2) Å]. In the crystal structure, the water mol-ecules link the mol-ecules into a three-dimensional network via inter-molecular N-H⋯O, O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds.

In the title isoniazid derivative, C(13)H(11)N(3)O(4)·2H(2)O, the Schiff base mol-ecule exists in an E configuration with respect to the acyclic C=N bond. An intra-molecular O-H⋯N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The essentially planar pyridine ring [maximum deviation = 0.0119 (8) Å] is inclined at a dihedral angle of 7.30 (4)° with respect to the benzene r...
