Abstract
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).
