Fusing 10-vertex -carborane anions with N-heterocyclic carbenes
Discovered by Knöth in 1964, the 10-vertex closo -carborane anion [HCB 9 H 9 1− ] is a classical bicapped square antiprism that contains an unusual pentacoordinate carbon center. Compared to its larger icosahedral cousin [HCB 11 H 11 1− ], few investigations have been made into its use as a weakly c...

multinuclear NMR spectroscopy, single crystal X-ray diffraction, and HRMS when possible.
