The title compound, N-hydroxy-4-phenylbut-3-en-2-imine [C10H11NO], was synthesized by reacting benzylideneacetone with
hydroxylamine hydrochloride in the presence of base. The structure of the compound was characterized by single crystal XRD data. It
crystallizes in the orthorhombic space group Pbc21 with unit-cell parameters: a= 5.591(6)Å, b=22.019(3)Å, c = 14.742(2) Å, β = 90.0º, Z =
4. The crystal structure has been elucidated by Direct methods and refined to a final R-value of 0.056 for 1535 observed reflections. In
the crystal molecules are linked by two N-H...N intermolecular H-bonds forming dimer. Molecules in the unit cell are packed together to
form well defined layers.
