Abstract

The α-diimine ligand 1,10-phenanthroline (phen) reacts with the activated cluster 1,2-Os₃(CO)₁₀(MeCN)₂ to afford the carbonyl-bridged cluster 1,1-Os₃(CO)₉(μ-CO) (phen), which has been characterized by IR and NMR spectroscopies and X-ray diffraction analysis. Replacement of the 1,5-cyclooctadiene (cod) ligand in 1,1-Os₃(CO)₁₀(cod) by phen proceeds sluggishly over a 24 h period, showing less than 5% conversion to 1,1-Os₃(CO) ₉(μ-CO)(phen).
