Abstract

Azomethine, derived from 3,5-dichlorosalicylaldehyde and allylamine, was synthesized and studied by X-ray diffraction. The compound exists in the enol-imine tautomeric form (the hydrogen atom is located on the oxygen atom). The structure is stabilized by the intramolecular О(1)–Н(1А)···N(1) hydrogen bond (О–Н, 0.82 Å; H···N, 1.91 Å; O···N, 2.580 Å; О–H–N, 138°).
