Coercive Fields Exceeding 30 T in the Mixed-Valence Single-Molecule Magnet (Cp^iPr5)₂Ho₂I₃.

ABSTRACT: Mixed-valence dilanthanide complexes of the type (Cp^iPr5)₂Ln₂I₃ (Cp^iPr5 = pentaisopropylcyclopentadienyl; Ln = Gd, Tb, Dy) featuring a direct Ln-Ln σ-bonding interaction have been shown to exhibit well-isolated high-spin ground states and, in the case of the Tb and Dy variants, a strong axial magnetic anisotropy that gives rise to a large magnetic coercivity. Here, we report the synthesis and characterization of two new mixed-valence dilanthanide compounds in this series, (Cp^iPr5)₂Ln₂I₃ (1-Ln; Ln = Ho, Er). Both compounds feature a Ln-Ln bonding interaction, the first such interaction in any molecular compounds of Ho or Er. Like the Tb and Dy congeners, both complexes exhibit high-spin
