Abstract

The reactions of [Mn₄(hmp)₆(NO₃) ₂(H₂O)₂](ClO₄)₂ with (Bu₄N)₂[CoX₄] (X = Cl, Br) in CH₃CN have been studied and the new heterometallic tetranuclear clusters [Co ^III ₂Mn^II ₂(hmp)₆Cl ₂(CH₃CN)₂]Mn^IICl₄· 3CH₃CN and [Co^III ₂Mn^II ₂(hmp)₆Br₂(CH₃CN) ₂]Mn^IIBr₄·4CH₃CN have been synthesized and characterized by TGA, electrospray ionization mass spectrometry, single-crystal X-ray diffraction, and magnetic measurements. The magnetic properties of the heterometallic clusters were analyzed by DFT and ab initio calculations. The first heterometallic tetranuclear clusters containing a [Co^III ₂Mn^II ₂] core have been synthesized and fully characterized. The magnetic susceptibility measurements in the temperature range 4-300 K reveal a rather strong intracluster antiferromagnetic coupling between the oxo-bridged Mn^II ions, in agreement with the results of DFT and ab initio calculations.
