Chelating anthraquinone ligands that contain nicotinyl and thiazolyl binding units have been synthesized. The complexation chemistry of these new ligands has also been explored using cadmium(II), lead(II), and ruthenium(II). The nicotinic substituted anthraquinone acts as a bidentate ligand, while the thiazolyl substituted anthraquinone binds in a tetradentate arrangement, not previously observed. Due to steric limitations, the number of these ligands that can coordinate to metal centers appears limited to bis-substituted products. Crystallographic data for both the free ligands and the cadmium and lead complexes are reported. Electrochemical data indicate that interaction does not take place between the intraannular carbonyl group and the neighboring metal centers within these complexes.
