Slow magnetic relaxation in a mononuclear 8-coordinate Fe(ii) complex†
Abstract
The synthesis and structure of an 8-coordinate Fe(II) compound [FeII(L1)2](ClO4)2 (1) with a [FeN4O4] core are reported. 1 exhibits uni-axial anisotropy for which a slow magnetic relaxation is observed under 1.4 kOe dc field. It is the first example of an 8-coordinate Fe(II) complex exhibiting field-induced single-molecule magnet (SMM) behaviour.
