Ethyl 2-[(carbamothioylamino)imino]propanoate

Abstract

The title compound, C6H11N3O2S, consists of a roughly planar molecule (r.m.s deviation from planarity = 0.077 Å for the non-H atoms) and has the S atom in an anti position to the imine N atom. This N atom is the acceptor of a strongly bent internal N—H...N hydrogen bond donated by the amino group. In the crystal, molecules are arranged in undulating layers parallel to (010). The molecules are linked via intermolecular amino–carboxyl N—H...O hydrogen bonds, forming chains parallel to [001]. The chains are cross-linked by Ncarbazone—H...S and C—H...S interactions, forming infinite sheets.
