N-[(E)-Thio-phen-2-yl-methyl-idene]-1,3-benzothia-zol-2-amine.

In the title thio-phene-derived Schiff base compound, C(12)H(8)N(2)S(2), the thio-phene ring is slighty rotated from the benzothia-zole group mean plane, giving a dihedral angle of 12.87†(6)°. The largest displacement of an atom in the mol-ecule from the nine-atom mean plane defined by the non-H atoms of the benzothia-zole ring system is 0.572†(1)†à , exhibited by the C atom at the 3-position of the thio-phene ring. In the crystal, weak C-H⋯S hydrogen bonds involving the thio-phene group S atom and the 4-position thio-phene C-H group of a symmetry-related mol-ecule lead to an infinite one-dimensional chain colinear with the c axis. The structure is further stabilized by π-π inter-actions; the distance between the thia-zole ring centroid and the centroid of an adjacent benzene ring is 3.686†(1)†à . The crystal studied was an inversion twin with the ratio of components 0.73†(3):0.27†(3).
