    • Abstract

       

      New pseudopolymorph of a O,N,N′-donor hydrazone ligand, 2-pyridylcarboxaldehyde isonicotinoylhydrazone (L) and its discrete complexes with K+ and Ba2+ have been reported. L forms isostructural dinuclear complexes with K+ when bromide and iodide were employed as counter anions. However, a monomeric complex in the case of Ba2+ with existence of coordinated as well as lattice perchlorate counter anions was observed. All compounds were characterized by single crystal X-ray analysis and other physicochemical techniques. Structural analysis and spectral features of all compounds are described in detail.
