Abstract

The mol­ecules of 2,6-dichloro­benzohydrazide, C7H6Cl2N2O, are linked into simple chains by a single N-H...O hydrogen bond, while in the isomeric compound 2,4-dichloro­benzo­hydrazide, the mol­ecules are linked by N-H...N and N-H...O hydrogen bonds into complex sheets comprising an inner polar layer sandwiched between two non-polar layers. In 4-amino-2-chloro­benzohydrazide monohydrate, C7H8ClN3O·H2O, the components are linked into a three-dimensional framework by a combination of O-H...O, O-H...N, N-H...N and N-H...O hydrogen bonds, and in 2-nitro­benzohydrazide, C7H7N3O3, a three-dimensional framework is formed by a combination of N-H...N and N-H...O hydrogen bonds
