1-Cyclohexyl-3-{(E)-[1-(pyridin-2-yl)ethylidene]amino}thiourea
Abstract
In the title thiourea derivative, C14H20N4S, the non-ring non-H atoms are approximately planar, with an r.m.s. deviation of 0.0720 Å. The pyridine ring is twisted out of this plane and makes a dihedral angle of 16.85 (13)° with it. The mean plane passing through the cyclohexyl ring is almost normal to the central plane [dihedral angle = 69.23 (8)°]. An intramolecular N—H...N(imine) hydrogen bond occurs. Centrosymmetric dimers are formed in the crystal structure via pairs of N—H...S hydrogen bonds, and these are connected into a supramolecular chain along the a axis via C—H...π(pyridyl) interactions.
