Abstrakt: A rare example of an organometallic terbium single-ion magnet is reported. A Tb 3+ -[1]ferrocenophane complex displays a larger barrier to magnetization reversal than its isostructural Dy 3+ analogue, which is reminiscent of trends observed for lanthanide-bis-phthalocyanine complexes. Detailed ab initio calculations support the experimental observations and suggest a significantly larger ground-state stabilization for the non-Kramers ion Tb 3+ in the Tb complex than for the Kramers-ion Dy 3+ in the Dy complex.
