چکیده
The title compound, C20H18N2S, was synthesized by the condensation reaction between p-tolu-idine and thio-phene-2,5-dicarboxaldehye in refluxing toluene with p-toluene-sulfonic acid added as catalyst. The mol-ecule lies on a twofold rotation axis and adopts an E orientation with respect to the azomethine bonds. The dihedral angle between the unqiue benzene ring and the least-squares plane [maximum deviation = 0.0145 (14) Å] containing the azomethine and thio-phene groups is 32.31 (6)°.

The whole molecule of the title Schiff base compound, C28H28N2O2, is generated by inversion symmetry. It is formed from two units of ortho-hy-droxy-naphthaldehyde bridged with 1,6-di-amino-hexane. The N atoms are protonated and, thus, the structure is a bis-zwitterionic compound in the solid state. The zwitterion shows strong intra-molecular N-H⋯O hydrogen bonds between the iminium N and the na...
