The clusters HRu3W(η5-Cp)(CO)11−x(PPh3)xBH (x=1, 2): preparations, characterizations and the crystal structure of HRu3W(η5-Cp)(CO)10(PPh3)BH

The clusters HRu3W(η5-Cp)(CO)11−x(PPh3)xBH (x=1, 2) have been prepared by reaction of PPh3 with HRu3W(η5-Cp)(CO)11BH after Me3NOMeCN-activation; HRu3W(η5-Cp)(CO)10(PPh3)BH has also been made by the reaction of HRu3(CO)8(PPh3)B2H5 with [(η5-Cp)W(CO)3]2. The cluster-bound hydrogen atoms respond to the charge density changes as PPh3 is introduced into HRu3W(η5-Cp)(CO)11BH, and proton chemical shift correlations are presented for this and related systems. The single crystal structure of HRu3W(η5-Cp)(CO)10(PPh3)BH has been determined.
