title: 2,3-Dimethoxybenzaldehyde isonicotinoylhydrazone chloroform monosolvate, and the mono- and dihydrates of 3,4,5-trimethoxybenzaldehyde isonicotinoylhydrazone: hydrogen-bonded supramolecular structures in one, two and three dimensions.
abstract: In 2,3-dimethoxybenzaldehyde isonicotinoylhydrazone chloroform monosolvate, C15H15N3O3.CHCl3, the hydrazone molecules are linked by a combination of N-H...N and C-H...N hydrogen bonds into chains from which the chloroform molecules are pendent. 3,4,5-Trimethoxybenzaldehyde isonicotinoylhydrazone forms two stoichiometric hydrates. In the monohydrate, C16H17N3O4.H2O, the components are linked into sheets by a combination of O-H...O, O-H...N and N-H...N hydrogen bonds, and in the dihydrate, C16H17N3O4.2H2O, a combination of O-H...O, O-H...N and N-H...O hydrogen bonds links the components into a three-dimensional framework structure.
