N′-[(E)-4-Bromobenzylidene]-1-benzofuran-2-carbohydrazide monohydrate
The title compound, C(16)H(11)BrN(2)O(2)·H(2)O, exists in a trans conformation with respect to the N=C bond [1.2815 (14) Å] and the benzofuran ring system forms a dihedral angle of 2.96 (5)° with the benzene ring. In the crystal, the ketone O atom accepts two O-H⋯O and one C-H⋯O hydrogen bond, and the water O atom accepts an N-H⋯O inter-action. Together, these lead to infinite layers lying para...

The title compound, C14H12FN3O, adopts an E conformation with respect to the azomethine bond. The pyridyl and fluoro-benzene rings make dihedral angles of 38.58 (6) and 41.61 (5)° respectively with the central C(=O)N2CC unit, resulting in a non-planar mol-ecule. The inter-molecular inter-actions comprise two classical N-H⋯O and N-H⋯N hydrogen bonds and four non-classical C-H⋯O and C-H⋯F hydroge...

The title compound, C(13)H(13)N(5)O, crystallizes with two mol-ecules in the asymmetric unit. The crystal structure is stabilized by intra-molecular N-H⋯N and N-H⋯O hydrogen bonds. The dihedral angles between the pyrazine ring and the 4-aminolphenyl ring are 2.5 (1) and 6.5 (1)° in the two molecules.

The title compound, C(16)H(11)ClN(2)O(2)·H(2)O, exists in an E conformation with respect to the N=C bond. The benzofuran ring system forms a dihedral angle of 1.26 (4)° with the benzene ring. In the crystal, mol-ecules are linked via (N,C)-H⋯O bifurcated acceptor hydrogen bonds and (O,O,C)-H⋯O trifurcated acceptor hydrogen bonds, forming layers parallel to the bc plane.
