title: Crystal structure of (1Z,2E)-cinnamaldehyde oxime.
abstract: The title compound, C9H9NO, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The conformation of the two mol-ecules differs slightly with the phenyl ring in mol-ecule A, forming a dihedral angle of 15.38 (12)° with the oxime group (O-N=C), compared to the corresponding angle of 26.29 (11)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked head-to-head by O-H⋯N hydrogen bonds, forming -A-B-A-B- zigzag chains along [010]. Within the chains and between neighbouring chains there are C-H⋯π inter-actions present, forming a three-dimensional structure.
