TTP型给体BDH-TTP与顺磁性阴离子[M(isoq)2(NCS)4](M= Cr,Fe)的自由基离子盐在7.6K显示出弱铁磁性。供体阳离子自由基(S= 1/2)和阴离子(S= 3/2(Cr),5/2(Fe))形成由紧密的分子间S → S接触所跨越的亚铁磁链,然后通过配体的π-π重叠相互反铁磁耦合。相邻阴离子的分子轴的非平行排列导致倾斜的自旋结构。
Radical-ion salts of a TTP-type donor BDH-TTP and paramagnetic anions [M (isoq) 2 (NCS) 4](M= Cr, Fe) show bulk weak ferromagnetism at 7.6 K. The donor cation radicals (S= 1/2) and anions (S= 3/2 (Cr), 5/2 (Fe)) form ferrimagnetic chains spanned by close intermolecular S⋯ S contacts, which are then antiferromagnetically coupled with each other through; h the π-π overlap of the ligands. The non-parallel alignment of the molecular axes of adjacent anions leads to the canted spin structure.
