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

Abstract

The ligand in the title complex, [ZnCl 2 (C 15 H 15 N 3 O)], 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. The geometry of the coordination polyhedron around the zinc ion is intermediate between a trigonal bipyramid and a square pyramid, but closer to the latter. 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.
