Abstract

Substituting effect of CF₃ to the Ru-based binuclear complex [{Ru^III(acac)₂}₂(μ-OEt)₂], in which S = 1/2 spin dimer takes the singlet ground state have been investigated by means of the magnetic susceptibility χ and the longitudinal nuclear spin relaxation rate T₁^-1 of ¹H/¹⁹F-NMR. In CF₃-substituted complex [{Ru^III(fhma)₂}₂(μ-OMe)₂], we have observed the prominent magnetic response both in χ and T₁^-1. This behavior is attributed to the slight change in the Ru valence state due to the substitution.
