Abstract

The magnetization of novel supramolecular grid structures consisting of four bis(bipyridyl)-pyrimidine ligands and four Co2+ ions was measured, We provide evidence for an antiferromagnetic coupling of the Co2spins, Investigations of microcrystals, powders, and solutions with the mean distance of the grids varying from 20 to 160 Angstrom showed that the coupling is solely of intramolecular origin and is not affected by long-range ordering. Thus, these grids form an almost ideal quantum spill system of four spins. This; is further supposed by low-temperature field-sweep measurements.
