2-[(1,3-Benzodioxol-5-ylmethylidene)amino]-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile

The title compound, C(17)H(14)N(2)O(2)S, crystallizes with two roughly planar mol-ecules in the asymmetric unit, in which the dihedral angles between the 1,3-benzodioxole-5-carbaldehyde moiety and the heterocyclic five-membered ring are 3.76 (5) and 5.33 (12)°. In each mol-ecule, a short C-H⋯S contact generates an S(5) ring. In the crystal, pairs of mol-ecules are linked by a weak C-H⋯N inter-action, forming dimers.
