(E)-N'-(2,4,6-Trihydroxy-benzyl-idene)isonicotinohydrazide sesquihydrate.

ABSTRACT: In the title compound, C(13)H(11)N(3)O(4)·1.5H(2)O, the pyridine ring forms a dihedral angle of 1.50?(6)° with the benzene ring. An intra-molecular O-H?N hydrogen bond forms a six-membered ring with an S(6) ring motif. In the crystal structure, one water mol-ecule is disordered over two positions around an inversion centre with site-occupancy factors of 0.5. Inter-molecular O-H?N, O-H?O, N-H?O and C-H?O hydrogen bonds consolidate the structure into a three dimensional network. A ?-? stacking inter-action with a centroid-centroid distance of 3.5949?(7)?Å is also present.
