Abstract

The title chiral bis-aldimine, C24H26N2S, was synthesized using a solvent-free Schiff condensation. The mol-ecule displays crystallographic C 2 symmetry, with the S atom lying on the twofold axis parallel to [100]. As a consequence of the (S,S) stereochemistry, the tolyl groups are oriented towards opposite faces of the thiophene core, giving a twisted conformation for the whole mol-ecule. Mol-ecules are arranged in the crystal in a herringbone-like pattern, without any significant inter-molecular contacts.
