Crystal structure of <i>N</i>′-[2-(benzo[<i>d</i>]thiazol-2-yl)acetyl]benzohydrazide, an achiral compound crystallizing in space group <i>P</i>1 with <i>Z</i> = 1

Abstract

In the molecule of the title compound, C 16 H 13 N 3 O 2 S, one hydrazinic nitrogen 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 antiperiplanar to the oxygen of the adjacent carbonyl group. The molecular packing is a layer structure determined by two classical hydrogen bonds, N—H...O=C and N—H...N thiazole . The space group is P 1 with Z = 1, which is unusual for an achiral organic compound.
