Herein, we describe an approach to cage metallasilsesquioxanes by self‐assembly with 1,2‐bis(diphenylphosphino)ethane as a key reactant. This approach allowed us to achieve a unique family of complexes that includes anionic tetra‐ and nonanuclear cage copper(II) sodium silsesquioxane and cationic copper(I) 1,2‐bis(diphenylphosphino)ethane components. Additional representatives of this intriguing metallasilsesquioxane family (Cu 9 Na 6 and Cu 9 Na 3 Cs 3 ) were obtained through the replacement of the original ethanol‐based reaction medium by DMSO. The fascinating structural peculiarities of all products were established by using XRD and topological studies. Initial tests for the application of the synthesized complexes as catalysts revealed their very high activity in the homogeneous oxidation of alkanes and alcohols to produce alkyl hydroperoxides, ketones, and amides.
