Geometry-Driven Field-Induced Single-Ion Magnetism in Hexagonal Bipyramidal Tb³⁺ and Ho³⁺ Complexes.

ABSTRACT: The synthesis of the precursors [Ln(L^N6en)(CH₃COO)₂](BPh₄)·nH₂O (Ln = Tb, n = 0, 1; Ln = Ho, n = 1, 2·H₂O), followed by a ligand exchange reaction with triphenylsilanolate, results in the isolation of the complexes {[Ln(L^N6en)(OSiPh₃)₂](BPh₄)}·2CH₂Cl₂ (Ln = Tb, 3·2CH₂Cl₂; Ln = Ho, 4·2CH₂Cl₂). Single-crystal X-ray diffraction studies of 3·2CH₂Cl₂ and 4·2CH₂Cl₂ revealed that both compounds adopt a hexagonal bipyramidal geometry. Magnetic characterization shows that the complexes behave as single-ion magnets (SIMs)
