Abstract : In the search for novel impregnants for activated carbon to enhance its chemical activity, a variety of organometallic complexes containing transition metals which may be used as impregnants have been synthesized. Copper, chromium, cobalt and silver are the transition' metals employed. The ligands studied included triethylenediamine (TEDA), quinuclidine (QUIN), acetylacetonate (acac) and its fluoro-derivative, hexafluoroacetylacetonate (hfac), and some cyclic dienes such as 1,5-cyclooctadiene (1,5-COD). In all, three classes of organometallic complexes were studied. The first class consisted of metal salts using TEDA (or QUIN) as ligands. The second class consisted of transition metals using acetylacetone, and TEDA (or QUIN) as ligands. The last class consisted of transition metals, using acetylacetonate and cyclic dienes as ligands. In this report, the synthetic routes and the characterization of these organometallic complexes obtained by various spectroscopic techniques are detailed.
