title: 1-(1-Phenyl-ethyl-idene)carbonohydrazide.
abstract: The title compound, C(9)H(12)N(4)O, crystallizes with two independent mol-ecules in the asymmetric unit. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen bonds link the mol-ecules into paired ribbons propagated in [100]. The crystal studied was a twin (twin law 00/00/001) with a minor component of 25%.
