Abstract: | The clusters Fe2Ru(CO)12–n(CNBut)n (3, n=1; 4, n=2), FeRu2(CO)12–n(CNBut)n (5, n=1, 6, n=2) and FeRu2(CO)11(CNCy) (5a) have been prepared by direct substitution from the parent carbonyl precursors Fe2Ru(CO)12 (1) and FeRu2(CO)12 (2). All compounds have been characterized spectroscopically and clusters 3, 4, 5, and 6 by single crystal X-ray determinations. In all cases, the isonitrile ligands adopt axial or pseudo-axial positions on a ruthenium atom. The structures of 3–5 are very similar to their parent clusters, but the extent of metal framework disorder is significantly less. Cluster 6 adopts the same C2v Fe3(CO)12 type structure as 4, and thus differs markedly from the parent compound 2, which has a D3 structure . |
