N'-[(E)-3-Indol-3-ylmethyl-ene]isonicotino-hydrazide monohydrate.

ABSTRACT: Crystals of the title compound, C(15)H(12)N(4)O·H(2)O, were obtained from a condensation reaction of isonicotinylhydrazine and 3-indolylformaldehyde. The mol-ecule assumes an E configuration, with the isonicotinoylhydrazine and indole units located on the opposite sites of the C=N double bond. In the mol-ecular structure the pyridine ring is twisted with respect to the indole ring system, forming a dihedral angle of 44.72?(7)°. Extensive classical N-H?N, N-H?O, O-H?O and O-H?N hydrogen bonding and weak C-H?O inter-actions are present in the crystal structure.
