1,5-Bis[(E)-cyclopentylidene]thiocarbonohydrazide

Abstract

In the title molecule, C11H18N4S, an intramolecular N—H...N hydrogen bond [N...N = 2.558 (3)Å] is observed. The two cyclopentyl rings are disordered between two conformations in 1:1 and 2:1 ratios. In the crystal structure, weak intermolecular N—H...S hydrogen bonds [N...S = 3.547 (3) Å] link pairs of molecules into centrosymmetric dimers.
