Encapsulation of paramagnetic 3d1-vanadium(IV) in an antiferromagnetically coupled dodecanuclear copper(II) cage.
A mixed metal cluster [Cu12VO5L6] of a pentadentate Schiff base (H3L) containing vanadium(IV) in a dodecanuclear copper(I) cage is prepared by vanadyl templated self assembly of dicopper(II) precursor and the structurally characterized complex shows antiferromagnetic coupling involving copper(II) centers, which leads close to diamagnetism for the Cu(II) cage below 40 K in the presence of an encapsulated paramagnetic 3d1-V(IV) atom.
