Different weak inter-actions in the crystals of three isomeric (E)-N-methyl-N'-(nitro-benzyl-idene)-2-(thio-phen-2-yl)acetohydrazides.

ABSTRACT: The crystal structures of three isomeric (E)-N-methyl-N'-(nitro-benzyl-idene)-2-(thio-phen-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, mol-ecules are linked by various weak inter-actions (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.
