biostudies-literatureUnknown65(Pt 12)Qian SSIn the crystal structure of the title Schiff base compound, C(18)H(20)N(2)O(4)S(2), the mol-ecule lies across a crystallographic inversion centre. The torsion angle of the N-C-C-N fragment is 180°, as the inversion centre bis-ects the central C-C bond. The crystal packing is stabilized by C-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions with a centroid-centroid distance of 3.913 (2) Å.Acta crystallographica.
