Supramolecular dication structures, ( CHDA 2+ )(crown ethers) and ( CHDMA 2+ )(crown ethers) complexes, were introduced as counter cations to [Ni(dmit) 2 ] − anions (S=1/2 spin) ( CHDA 2+ = trans -1,4-cyclohexanediammonium; CHDMA 2+ =1,4-bis(methylammonium)cyclohexane; dmit 2− =2-thioxo-1,3-dithiole-4,5-dithiolate; crown ethers=[12]crown-4, [15]crown-5, or [18]crown-6). The cyclohexane rings, with the –NH 3 + or –CH 2 –NH 3 + substituents at trans -1,4-positions, arrange into the crown ethers… CONTINUE READING
