Abstract

The title compound (C20H16N2S3) is monoclinic, witha=31.550(9),b=8.504(3),c=14.745(3) Å,β=114.14(3)°,Z=8 and space groupC2/c. The structure was solved by direct methods and refined toR=0.038 for 3012 reflections. The molecule exists in an uncommon conformation. Two quinoline moieties are nearly perpendicular to each other (80.9(3)°). Both methylthio groups have different orientation (the 4-SCH3 group is nearly perpendicular and the 3′-SCH3 is nearly coplanar to the quinoline moieties). Two pairs of sulfur atoms in ortho-positions remain in very close contact. The conformation of the molecule explains an unusual1H NMR spectrum.
