Crystal structure of (E)-N′-(5-bromo-2-hydroxybenzylidene)nicotinohydrazide monohydrate

Abstract

The title compound, has an E conformation about the C=N bond and the mol­ecules is planar (r.m.s. deviation for all non-H atoms = 0.021 Å). In the crystal, the lattice water mol­ecule (Ow) links the mol­ecules via Ow—H⋯O, Ow—H⋯N and N—H⋯Ow hydrogen bonds, forming sheets lying parallel to (100).
