DOI: 10.1002/ejic.201700492
Abstract: Analysis of the literature structures [(CO)(PPh3)2MC2B9H11] and [(CO)2(PPh3)MC2B9H11] suggests that in [L3MC2B9H11] metallacarboranes the trans influence of CO is greater than that of PPh3. Extending this study to the [L4MC2B9H11] system the new molybdacarboranes [3,3,3-(CO)3-3-PPh3-3,1,2-closo-MoC2B9H11]… read more here.
