     The ¹¹B spectra of B₁₀H₁₀CN(Me)₃ and the salt Na^⊕[B₁₀H₁₀CH]^⊖ were essentially similar and the structure was rationalized in terms of a “clovo” octadecahedral structure of C_2v symmetry (65).

     Evidence to support an octadecahedral arrangement of boron atoms in [B₁₁H₁₁]²⁻ is provided by structural data for derivatives such as [B₁₁H₁₀(SMe₂)]⁻.
