<p>The present invention provides a method for binding gaseous molecules, the method comprising contacting gases comprising the gaseous molecules with trivaient metal complexes. Typically, the gaseous motecuies comprise polar molecules of greenhouse gases, especially the oxides of carbon, nitrogen and sulphur. Preferably, the trivaient metai complexes comprise complexes of actinide metals, most preferably uranium. The method is particularly useful in the removal of so-called greenhouse gases from the atmosphere, and is therefore of potentially very great value environmentally. The invention also provides trivaient metal complexes comprising sandwich complexes of trivaient metals selected from transition metals and actinide metals, the complexes comprising two ligands selected from pentalenyl, indenyl, cyclopentadienyl and cyclooctatetraene ligands. The invention further provides a method for the preparation of the trivaient metal complexes.</p> |
