Synthesis and characterization of tetraruthenaborane clusters: Molecular structure of (HRu sub 4 (CO) sub 12 Au sub 2 (PPh sub 3 ) sub 2 B)
- University Chemical Laboratory, Cambridge (England)
- Univ. of Delaware, Newark (USA)
The tetraruthenaborane cluster HRu{sub 4}(CO){sub 12}BH{sub 2} (1) has been synthesized and characterized spectroscopically. Deprotonation to (HRu{sub 4}(CO){sub 12}BH){sup {minus}} (2) occurs via the loss of an Ru-H-B bridging proton. Compounds 1 and 2 are structural analogues of the ferraboranes HFe{sub 4}(CO){sub 12}BH{sub 2} and (HFe{sub 4}(CO){sub 12}BH){sup {minus}}, although, compared to (HFe{sub 4}(CO){sub 12}BH){sup {minus}}, 2 exhibits a higher activation barrier for endo-hydrogen exchange, in line with the increased M-H-M and M-H-B bond energies in going from M = Fe to Ru.
