Abstract
We report the synthesis, structure and magnetic investigations of a new Dy 3+ heteroleptic complex [Dy(tBu 4 Carb)(o-Me 2 N-C 6 H 4 CH 2) 2 ]•C 7 H 8 (1) (tBu 4 Carb = 1,3,6,8-Tetra-tert-butyl-9H-carbazole, o-Me 2 N-C 6 H 4 CH 2) 2 = oN ,N-dimethylaminobenzyl). The carbazolyl ligand exhibits an unprecedented 5 -interaction with the magnetically anisotropic dysprosium(III) ion resulting in a genuine zero-field singlemolecule magnet behavior.
