Assigned cluster 11B and 1H NMR properties of [3‐(η6‐C6Me6)‐closo‐3,1,2‐RuC2B9H11

Abstract

AbstractThe cluster 11B chemical shifts in members of the important class of closo‐3,1,2‐metalladicarbaboranes were previously unassigned, and their cluster 1H chemical shifts previously unmeasured. The use of [11B11B]‐COSY and 1H‐{11B} NMR spectroscopy to measure and assign the cluster 11B and 1H chemical shifts of (previously unreported) [3‐(η6‐C6Me6)‐closo‐3,1,2‐RuC2B9H11] as a model compound is reported. The 11B shielding patterns of this species and the nonmetalla simple carbaborane analogue [1,2‐C2B10H12] are compared and briefly discussed.
