Crystal structure of (1Z,2E)-cinnamaldehyde oxime

Abstract

The title compound, C9H9NO, crystallized with two independent mol­ecules (A and B) in the asymmetric unit. The conformation of the two mol­ecules differs slightly with the phenyl ring in mol­ecule 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 mol­ecule B. In the crystal, the A and B mol­ecules 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 inter­actions present, forming a three-dimensional structure.
