Meanings
- not comparableIn the form of an octadecahedron.
Evidence to support an octadecahedral arrangement of boron atoms in [B₁₁H₁₁]²⁻ is provided by structural data for derivatives such as [B₁₁H₁₀(SMe₂)]⁻.

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 C₂ᵥ symmetry (65).

Mooney, editor, Annual Review of NMR Spectroscopy, volume 2, London; New York, N.Y.: Academic Press, →LCCN, page 257Four highest maxima of the residual electron density map present inside the octadecahedral cages of the framework were assigned to the disordered protonated quinuclidine [9].
