Abstract

Magnetic susceptibilities and electron paramagnetic resonances (EPRs) of coordination compounds of triangular trinuclear [Ru₂M(μ-CH₃COO)₆(μ ₃-O)(py)₃]ⁿ⁺, M=Mn(II), Fe(III), Cr(III), Ni(II), or Co(II) ions, were observed. The results were analysed by the spin vector model. Effective Bohr magneton numbers showed that the main superexchange interaction within each cluster was of the order of J/k=-300 K. This was considered to be working through μ₃-O. Together with some weaker superexchange interactions through μ-CH₃COO paths, fittings with the susceptibilities of the model were tried. EPR signals at temperatures of a few K were characteristic of each M ion. M=Mn(II) and M=Fe(III) were at high spin states of S=5/2 and M=Co(II) was at a low spin state of S=1/2. Temperature dependences of EPR signals are discussed.
