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.
