Abstract

A rare example of an organometallic terbium single-ion magnet is reported. The new Tb3+-[1]ferrocenophane complex (1) displays a larger barrier to magnetization reversal than its isostructural Dy3+ analogue (2) 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 Tb3+ in 1 than for the Kramers-ion Dy3+ in 2.
