چکیده
In the title compound, C(8)H(9)BrN(2)O, the 1-bromo-4-methyl-benzene group and the formic hydrazide moiety [r.m.s. deviations of 0.0129 and 0.0038 Å] are oriented at a dihedral angle of 80.66 (11)°. In the crystal, mol-ecules are linked via strong N-H⋯O hydrogen bonds, leading to the formation of chains in the [010] direction. These chains are linked via weaker N-H⋯N and N-H⋯O hydrogen bonds, with R(2) (2)(7) and R(3) (2)(7) ring motifs, forming a two-dimensional network parallel to (001).

The title compound, C(10)H(8)N(4)O(4)·H(2)O, was obtained by the reaction of 5-hy-droxy-2-nitro-benzaldehyde with cyano-acetohydrazide in methanol. The non-H atoms of the hydrazone molecule are approximately coplanar, with a mean deviation from the least-squares plane of 0.056 Å. In the crystal, mol-ecules are linked by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, generating a three-dimensional network.

The title compound, C(9)H(12)N(2)O(3), was synthesized by the reaction of ethyl 2-(4-meth-oxy-phen-oxy)acetate with hydrazine hydrate in ethanol. In the acetohydrazide group, the N-N bond is relatively short [1.413 (2) Å], suggesting some degree of electronic delocalization in the mol-ecule. In the crystal, mol-ecules are linked into sheets lying parallel to the ab plane by N-H⋯N and N-H⋯O hydr...
