Abstract

[Na₁₁(O^tBu)₁₀(OH)], a hydroxide enclosing 21-vertex cage compound, was found to crystallize from mixtures of sodium tert.butanolate with sodium hydroxide. Its structure can be derived from the known (NaO^tBu)₆-hexaprismane by replacing one butanolate unit with OH⁻ and capping the latter with five additional units of NaO^tBu. The hydroxide shows a signal at −3.21 ppm in the ¹H NMR spectrum.
