Replacement of the 1,5-cyclooctadiene (cod) ligand in 1,1-Os3(CO)10(cod) by phen proceeds sluggishly over a 24h period, showing less than 5% conversion to 1,1-Os3(CO)9(μ-CO)(phen). Graphical abstract: α-Diimine Chelation at a Triosmium Cluster: Synthesis and X-ray Structure of 1,1-Os 3 (CO) 9 (μ-CO)(1,10-phen) Bhaskar Poola, Xiaoping Wang, and Michael G. Richmond The reaction between the triosmium cluster 1,2-Os3(CO)10(MeCN)2 and 1,10-phenanthroline yields 1,1-Os3(CO)9(μ-CO)(phen) at room temperature. The presence of a bridging carbonyl group in the product cluster has been observed by IR spectroscopy and confirmed by X-ray crystallography.
