Abstract

Chemistry of coordination compounds is an interesting and growing field of research; design and construction of novel compounds with favorable properties have fascinating applications ranging from nanotechnology, catalysis, macromolecular crystallography and medicine. O-donor ligands are of particular interest because their complexes with biologically important metals have potential medical applications. Furthermore, planar and rigid heterocyclic N-donor π-electron-deficient ligands, are widely used in supramolecular chemistry and/or in the molecular biology as DNA cleaving reagents and etc. The aim of the present study is to produce an organized structure possessing a combination of both properties using the mixed ligands. In this work, we select pyridine-2,5-dicarboxyxlic acid N-oxide -pydco- as a versatile O-donor ligand with -COOH groups in a p-arrangement. It can be used to construct coordination polymers or link monomeric or dimeric compounds by hydrogen bonding through its uncoordinated carboxylate group at the position 5 [1-3]. Herein, we report successful preparation of a new coordination complex based on pydco, 2,2\\\\\\\\\\\\\\\'-bipyridine -bpy- and zinc metal, which is characterized by physico-chemical approaches such as elemental analysis -CHN-, IR spectroscopy and melting point. Based on our data it may be formulated as [Zn-pydco--bpy--H2O-2]·4H2O. This category of complexes remains little-investigated in aspects such as single crystal X-ray diffraction, supramolecular interactions and biological tests; therefore we intend to extend our studies.
