‘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.
