title: 3-Amino-5-(piperidin-1-yl)thio-phene-2,4-dicarbonitrile.
abstract: In the title compound, C(11)H(12)N(4)S, the thio-phene ring is roughly planar, with a maximum deviation of 0.012 (1) Å for the S atom, and makes a dihedral angle of 7.89 (8)° with the mean plane of the piperidine ring, which is in a chair conformation. The crystal packing is stabilized by pairs of centrosymmetric inter-molecular N-H⋯N hydrogen bonds, which results in the formation of a step-wise chain parallel to [10[Formula: see text]].
