Inverse crown ether complexes: extension to potassium through the synthesis of [{[(Me3Si)(2)N](4)K2Mg2(O-2)}(infinity)], a peroxo- centred macrocycle linked into infinite chains by intermolecular K center dot center dot center dot CH3(SiMe2) interac

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.
