2-Amino-4-(2-naphthyl)­thio­phene-3-carbo­nitrile.

A new type of thio­phene derivative with potential pharmacological activity, viz. 2-amino-4-(2-naphthalyl)­thio­phene-3-carbo­nitrile, C15H10N2S, has been prepared and studied by NMR and single-crystal X-ray diffraction techniques. The mol­ecule contains two different groups, naphthalene and thio­phene, which are nearly perpendicular to one another. In the crystal structure, a hydrogen bond, with a D⋯ A distance of 3.033 (3) Å, is present between the amino substituent and the carbo­nitrile N atom of a symmetry-related mol­ecule. The crystal structure also includes one C—H⋯π interaction. [ABSTRACT FROM AUTHOR]
