(E)-4-Amino-N′-(5-bromo-2-hydroxybenzylidene)benzohydrazide monohydrate
In t the title compound, C(14)H(12)BrN(3)O(2). H(2)O, the conformation of the C=N double bond in the hydrazide Schiff base mol-ecule is E. The dihedral angle between the benzene rings is 48.01 (11) °. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. In the crystal, mol-ecules are linked through N-H⋯O (bifurcated acceptor) and O-H⋯O hydrogen bonds, forming two-dimensional network...

In the title compound, C(15)H(15)N(3)O(3)·H(2)O, the hydazide Schiff base mol-ecule shows an E conformation around the C=N bond. An intra-molecular O-H⋯N hydrogen bond makes an S(6) ring motif. The dihedral angle between the substituted phenyl rings is 23.40 (11)°. The water mol-ecule mediates linking of neighbouring mol-ecules through O-H⋯(O,O) hydrogen bonds into infinite chains along the a a...

The title compound, C15H13BrN2O3·H2O, exists in an E conformation with respect to the azo-methane C=N double bond. The benzene and phenyl rings form dihedral angles of 0.46 (2) and 4.90 (3)°, respectively with the central C(=O)N2C unit. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, some hydrazide mol-ecules are replaced by mol-ecules of the 6-bromo isomer. The Br atom from this...

The Schiff base mol-ecule in the title compound, C(14)H(11)BrN(2)O(4)·H(2)O, is almost planar with an r.m.s. deviation for the non-H atoms of 0.16 Å. In the crystal structure, the Schiff base mol-ecules and the water mol-ecules are linked together by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, leading to layers parallel to the bc plane. An intra-molecular O-H⋯N hydrogen bond involving the i...

In the title compound, C(16)H(15)BrN(2)O(4)·H(2)O, the hydrazide mol-ecule is nearly planar, with a largest deviation from the mean plane through the non-H atoms of 0.106 (4) Å and a dihedral angle between the benzene rings of 1.98 (16)°. This mol-ecule adopts an E conformation about the C=N bond and an intra-molecular O-H⋯N hydrogen bond increases the rigidity. In the crystal, some mol-ecules ...
