Various chromium quinone complexes have been synthesized, yielding a 2:1 ratio of chromium to quinone, and can be used to study the kinetics of the oxidation of different alcohols.  In this research, the synthesis of certain chromium quinone complexes was attempted, using tetrahydroxy-1,4-benzoquinone (THQ) along with 2,2'-bipyridine and 1,10-phenanthroline ligands to occupy coordination sites on the chromium metal centers. The various compounds synthesized were analyzed by infrared spectroscopy and elemental analysis.  The two analyses confirmed that the bonding of the chromium to the quinone occurred through the ketone oxygen and a neighboring hydroxyl group.  The mono and bis bipyridine and phenanthroline complexes were synthesized, and he synthetic method and characterization data will be presented.
