Synthesis and structure of dichlorido{(E)-4-methyl-N′-[1-(pyridin-2-yl)ethylidene]benzohydrazide}zinc(II)

Abstract

The ligand in the title complex was obtained by a condensation reaction between p-tolyl hydrazide and 2-acetylpyridine. The ligand molecule bonds to the metal ion in a tridentate manner via its imino nitrogen atom, its carbonyl oxygen atom, and the nitrogen atom of the pyridine ring. In the extended structure, pairwise N—H⋯Cl hydrogen bonds generate inversion dimers and very weak C—H⋯Cl interactions link the dimers into sheets.
