The potassium salt of the [1‐H 2 N‐2‐F‐ closo ‐1‐CB 11 H 10 ] – anion ( 1 ) was obtained from an insertion reaction of Li 3 [7‐H 2 N‐ nido ‐7‐CB 10 H 10 ] with BF 3 · OEt 2 . Anion 1 was protonated to the neutral species 1‐H 3 N‐2‐F‐ closo ‐1‐CB 11 H 10 (H 1 ) and it was iodinated with ICl to the [1‐H 2 N‐2‐F‐ closo ‐1‐CB 11 I 10 ] – anion ( 2 ). All species were characterized by multinuclear NMR, IR, and Raman spectroscopy as well as by elemental analysis. The structure of H 1· (CH 3 ) 2 CO was studied by single‐crystal X‐ray diffraction and the experimentally determined bond lengths are compared to values derived from density functional calculations.
