Reaction of Double Cyclopalladated Azobenzenes with 2, 2'-Bipyridine

A set of novel Pd(II) dinuclear complexes [PdCl{;(µ 2-Cl)(­µ -AZB)Pd(bpy)] with an unprecedented structure have been prepared in acetone by the reaction of double cyclopalladated complexes {;(DMF)PdCl(µ -AZB)(DMF)PdCl}; with excess of 2, 2-bipyridine. Their structural and spectroscopic properties were determined by the X-ray diffraction analysis as well as by the 1H NMR, IR, UV-vis and fluorimetric studies. The crystal structure of all complexes revealed that two palladium atoms are bridged by chlorine atom and azobenzene ligand forming six-membered ring.
