title: Four substituted benzohydrazides: hydrogen-bonded structures in one, two and three dimensions.
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.
