Reversible syntheses of cyclopentadienylrhodium–triruthenium cluster complexes; crystal and molecular structure of (η-C5Me5)RhRu3(µ-H)4(CO)9
Abstract
The mixed metal complexes cpRhRu3(µ-H)2(µ-CO)(CO)9(cp =η-C5H5 or ηC5Me5) and (η-C5Me5) RhRu3(µ-H)4(CO)9(in which the four bridging hydrogen atoms have been located on an X-ray structure determination) are formed when H2 is bubbled through solutions of Ru3(CO)12 and the respective cpRh(CO)2 at 70–90 °C but, under 1 atm CO at 25 °C are easily disrupted into the starting materials, which are obtained with complete 13C-enrichment under 1 atm 13CO.
