Investigation of exchange Interaction in heterometallic complexes MIICrIII (M = Mn, Co, Ni, Cu, Zn)

The reaction of bis(phenanthroline)metal(II) cations (M = Mn2+, Co2+, Ni2+, Cu2+, Zn2+) with bis(oxalato)chromium(III) anions in water/ethanol solution gives rise to a series of compounds with oxalate-bridged cations, [{; ; ; ; M(phen)2}; ; ; ; 2(μ- C2O4)]1/2[Cr(phen)(C2O4)2]·2H2O [MnCr, CoCr, NiCr, CuCr, ZnCr]. The temperature dependence of magnetic susceptibility χ(T) indicates different magnetic super exchange interactions taking place in homodinuclear oxalate-bridged cations containing Mn2+, Co2+, Ni2+ and Cu2+. Oxalate ligands mediate ferromagnetic coupling of Cu2+ metal cations in CuCr with J = 3.45cm-1, whereas in MnCr, CoCr, NiCr, antiferromagnetic interactions are observed between Mn2+, Co2+ and Ni2+ cations, with J = - 2.48cm-1, -9.61cm-1 and -23.89cm-1 respectively. Presence of large zero- field splitting parameters for Cr3+ ion (from mononuclear anion) indicates significant influence of octahedral distortions on magnetic properties of the investigated compounds. Own software is developed in order to fit all magnetic parameters at the same time.
