Abstract The cluster 11 B chemical shifts in members of the important class of closo ‐3,1,2‐metalladicarbaboranes were previously unassigned, and their cluster 1 H chemical shifts previously unmeasured. The use of [ 11 B 11 B]‐COSY and 1 H‐{ 11 B} NMR spectroscopy to measure and assign the cluster 11 B and 1 H chemical shifts of (previously unreported) [3‐(η 6 ‐C 6 Me 6 )‐ closo ‐3,1,2‐RuC 2 B 9 H 11 ] as a model compound is reported. The 11 B shielding patterns of this species and the nonmetalla simple carbaborane analogue [1,2‐C 2 B 10 H 12 ] are compared and briefly discussed.
