Osmium(II) Complex of Pyridine-2,6-dicarboxylate Ligand : Synthesis, Structure, Electrochemistry and Photophysical Property

In this study, we used pyridine-2,6-dicarboxylic acid and 2,2¡¦:6¡¦,2¡¨ - terpyridine as ligands to form the neutral osmium complex. The metal center showed a reversible redox wave at E1/2 = 0.36 V, and there was also an irreversible redox wave at E1/2 = -1.50 V. The complex had a pseudo-octahedral structure, which contained a C2 axis and both a H2O and ether molecule were inside. There was a intermolecular £k-£k interaction between terpyridines, and H-bonding between H2O and the carbonyl group of pyridine-2,6-dicarboxylate ligand. Computer deconvolution of the MLCT band with three Gaussian lines and two lines of ligand-centered band was carried out.
