Abstract

Two mononuclear, seven-coordinate Co(II) and Fe(II) complexes [Co^II(BPA-TPA)](BF₄)₂ (1-Co) and [Fe^II(BPA-TPA)](ClO₄)₂ (2-Fe) with a capped trigonal prismatic coordination geometry have been synthesized from the pentapyridyldiamine (BPA-TPA) ligand. 1-Co exhibits easy plane anisotropy in which slow magnetic relaxation is observed under a 1.0 kOe dc field. It is the first example of a single-ion magnet (SIM) of a 3d transition metal ion with a capped trigonal prismatic configuration. 2-Fe is not a SIM at 1.8 K.
