2-[(5-Methyl­thio­phen-2-yl)methyl­idene]malono­nitrile

There are two independent molecules in the asymmetric unit of the title compound, C₉H₆N₂S, which is an inter­mediate compound of a cardiovascular drug. The two molecules are nearly planar, displaying dihedral angles of 3.5 (2) and 5.7 (2)° between the thiophene ring and the malononitrile moiety. In the crystal, C—H...N inter­actions lead to the formation of a sheet structure that packs in a parallel fashion.
