(E)-N-[(Benzo­[b]­thio­phen-3-yl)­methyl­ene]-N′-(2,5-di­chloro­phenyl)­hydrazine

The title compound, C₁₅H₁₀Cl₂N₂S, crystallizes in the centrosymmetric space group P2₁/c with one mol­ecule in the asymmetric unit. The mol­ecule assumes an approximately planar configuration and has an E geometry about the azomethine C=N double bond. The crystal structure is stabilized by extensive hydrogen bonding.
