The ketyl‐induced reaction of [Ru 3 (CO) 12 ] with N , N ‐bis(diphenylphosphanyl) n ‐propylamine (dpppra) in THF resulted in the expected metal cluster [Ru 3 (CO) 10 (μ‐dpppra)] ( 2 ) in high yield. Compound 2 reacted in refluxing heptane with PBu t 2 H affording a new derivative of the rare type of 46‐valence electron clusters [Ru 3 (μ‐CO)(CO) 4 (μ‐dpppra)(μ 3 ‐H)(μ‐H)(μ‐P t Bu 2 ) 2 ] ( 3 ) in good yield. The related cluster [Ru 3 (μ‐CO)(CO) 4 (μ‐dppa)(μ 3 ‐H)(μ‐H)(μ‐P t Bu 2 ) 2 ] ( 4 ) (dppa=bis(diphenylphosphanyl)amine) was obtained in a similar manner in comparable yields. Compounds 2 , 3 , and 4 were spectroscopically characterized and their molecular structures in the solid were confirmed by single‐crystal X‐ray analysis.
