Abstract

In the mol-ecule of the title compound, C₁₆H₁₃N₃O₂S, one hydrazinic nitro-gen atom is essentially planar, but the other is slightly pyramidalized. The torsion angle about the hydrazinic bond is 66.44 (15)°. Both hydrazinic hydrogen atoms lie anti-periplanar to the oxygen of the adjacent carbonyl group. The mol-ecular packing is a layer structure determined by two classical hydrogen bonds, N-H⋯O=C and N-H⋯N_thia-zole. The space group is P1 with Z = 1, which is unusual for an achiral organic compound.

Keywords: crystal structure; hydrazide; hydrogen bond; space group P1; thiazole.
