A naphthalene-thiophene-naphthalene diazomethine triad solvated with dichloromethane

W. G. Skene and S. Dufresne

Abstract: The highly conjugated title compound, (E)-N-{(5-[(E)-1-naphthyliminomethyl]-2-thienylmethylene}naphthalen-1-amine dichloromethane hemisolvate, C₂₆H₁₈N₂S·0.5CH₂Cl₂, exhibits a non-planar yet extended configuration. The naphthyl ring systems are twisted 33.8 (4) and 32.6 (5)° out of the mean plane that passes through the thiophene ring. The nitrogen-containing double bonds are ca 0.05 Å shorter than their carbon analogues and both adopt the thermodynamically favourable E configuration.
