title: 2-[(5-Methyl-thio-phen-2-yl)methyl-idene]malono-nitrile.
abstract: There are two independent molecules in the asymmetric unit of the title compound, C9H6N2S, which is an inter-mediate 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 inter-actions lead to the formation of a sheet structure that packs in a parallel fashion.
