1-(Cycloheptylidene)thiosemicarbazide

Abstract

The asymmetric unit of the title compound, C8H15N3S, contains two independent molecules. In both molecules, the seven-membered cycloheptane ring adopts a chair conformation. An intramolecular N—H...N hydrogen bond is observed in both molecules, forming S(5) graph-set motifs. In the crystal, the two independent molecules are connected through N—H...S hydrogen bonds, forming dimers which are in turn further connected by N—H...S hydrogen bonds into chains along [010].
