چکیده
The mol-ecule of the title compound, C(13)H(11)N(3)O(5)S, shows a phenyl group and an almost planar intra-molecularly hydrogen-bonded N'-(2-hydr-oxy-5-phenyl-ebenzyl-idene)hydrazino group disposed about the S atom. Adjacent mol-ecules are linked by N-H⋯O(nitro) hydrogen bonds, producing a linear chain that runs along the b axis of the unit cell.
