Crystal structure of diethyl 2-[(2-sulfanylquinolin-3-yl)methylidene]malonate

Abstract

In the title compound, C17H17N O4S, the quinoline ring system is nearly planar, with a maximum deviation of 0.0496 (16) Å. A weak intramolecular C—H...O interaction is observed. In the crystal, C—H...O, S—H...N and π–π stacking interactions between the fused benzene ring of quinoline and the pyridine moieties [shortest centroid–centroid distance = 3.6754 (11) Å] are observed. Inversion-related weak C—H...O intermolecular interactions diagonally along [010], withR22(10) ring motifs, and S—H...N intermolecular interactions diagonally along [100], withR22(8) ring motifs, are present, forming a three-dimensional network structure. No classical hydrogen bonds are observed.
