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.
