‘Inverse crown ether’ complexes: extension to potassium through the synthesis of [{[(Me₃Si)₂N]₄K₂Mg₂(O₂)}_∞], a peroxo-centred macrocycle linked into infinite chains by intermolecular K⋯CH₃(SiMe₂) interactions

Abstract

The title compound represents the first potassium example of a novel class of amide-supported heterobimetallic macrocycle having a dicationic (N₄K₂Mg₂)²⁺ octagonal ring framework surrounding a dianionic (O₂)^2– core.
