Supramolecular self-assembly of a toroidal inclusion complex, [NH4][Co8(MeCO2)8(OMe)16][PF6]
Abstract
Diamagnetic [NH4][Co8(MeCO2)8(OMe)16][PF6], a compound with eight cobalt atoms bridged by methoxy and acetato ligands so as to form a planar ring with an ammonium ion at its centre, is isolated from the reaction between cobalt(III) acetate and methanol in the presence of NH4PF6.
