title: 2-(1H-Benzotriazol-1-yl)acetohydrazide.
abstract: The title compound, C(8)H(9)N(5)O, was synthesized by the reaction of ethyl 2-(benzotriazol-1-yl)acetate with hydrazine hydrate in ethanol. In the amide group, the C-N bond is relatively short [1.3283 (16) Å], suggesting some degree of electronic delocalization in the mol-ecule. In the crystal structure, mol-ecules are linked into infinite chains along the a axis by inter-molecular O-H⋯N hydrogen bonding.
