Abstract
Zinc complexes of Schiff base ligands exhibit
interesting properties which could be exploited for potential applications as
catalysts and models for biochemical systems.
In this study, we report of the synthesis of a new zinc Schiff base complex,
bis(N’-(pyridine-3-carboxaldehyde)
isonicotinoylhydrazone) zinc(II), which has been characterized by
physico-chemical methods. The X-ray single crystal structure of the complex has
also been determined. The Schiff base ligand is bonded to the metal in a monodentate manner, coordinating
through the pyridine N-atom, as shown from spectral studies. The crystal
structure shows the zinc atom bonded to two Schiff bases and four aqua ligands, with each Schiff base ligand
coordinating through its pyridine N-atom forming a distorted octahedral ZnN2O4 complex. Two water molecules and two nitrate ions found in the crystal
structure link the different monomers through hydrogen bonding to form a
layered supramolecular structure.
