Abstract

The crystal structures of three isomeric (E)-N-methyl-N′-(nitro­benzyl­idene)-2-(thio­phen-2-yl)acetohydrazides (formula C14H13N3O3S) are described, with the nitro group in ortho, meta and para positions in the benzene ring. In each crystal structure, mol­ecules are linked by various weak inter­actions (C—H⋯O and C—H⋯π bonds, and π–π stacking), leading to three-dimensional networks in each case, but with little similarity between them.
