Co2+(15-crown-5) magnetic supramoleccular cation in [Ni(dmit)(2)](-) pi-spin system
Magnetic cation of Co2+ was incorporated in a monovalent [Ni(dmit)(2)](-) (2-thioxo-1,3-dithiole-4,5-dithiolate) salt by using the supramolecular framework of 15-crown-5. The pi-spins of [Ni(dmit)(2)](-) formed a one-dimensional Heisenberg antiferromagnetic linear chain, while the d-spin of Co2+ behaved as a free S = 3/2 spin within the crystal.
