Chemists are trained to recognize aromaticity semi-intuitively, using pictures of resonance structures and Frost-Musulin diagrams, or simple electron-counting rules such as Hückel’s 4n + 2/4n rule. To quantify aromaticity one...

Metal Carbonyl Clusters

<p>The series for carbonyl clusters of transition metals have been developed. They may be considered to be formed with a fragment centered around the 14 electron valence content. The capping series are based on the fragment of 12 electron valence content. The formulas of clusters can be decomposed into series from which the shapes of clusters may be predicted. The electron counting numbers of carbonyl clusters can be identified.</p>
