Antiferromagnetic interaction achieved by a 3-D supramolecular Cu-II complex with pyrazino-fused TTF as the ligand, [CuCl2(BP-TTF)]
The diffusion reaction of TBA(2)Cu(II)Cl(4) (TBA = tetrabutylammonium) and a N-containing organic donor, BP-TTF [=bis(pyrazino)-tetrathiafulvalene], yielded a 3-D supramolecular Cu complex, [CuCl2(BP-TTF)] (1). The magnetic measurement of 1 exhibits an antiferromagnetic interaction by fitting a Bonner-Fisher model from 2 to 300 K with S = (1)/(2) and J = -3.5 K between Cu-II mediated by self-assembling donor columns.
