4-(2-Sulfanylidene-1,3-benzothiazol-3-yl)butan-2-one

Abstract

In the title compound, C11H11NOS2, the benzine ring is coplanar with the thiazole ring, making a dihedral angle of 0.81 (1)°. In the crystal, adjacent molecules are connected into a helical chain along the b axis by S...S contacts [3.4345 (18) Å]. These helical chains are further assembled into a three-dimensional supermolecular network by intermolecular C—H...O hydrogen bond between aromatic ring H atoms and carbonyl groups.
