Long-range superexchanged magnetic interaction observed in heterometallic complex: {[Fe-II(Tpms)(CN)(3)][Mn-II(H2O)(2)(DMF)(2)}] center dot DMF

摘要

A new tri-cyanometalate building block for heterometallic complexes, [PPh4](2)[Fe-II(Tpms)(CN)(3)] (2) (PPh4 = tetraphenylphosphonium; Tpms = tris(pyrazolyl) methanesulfonate), has been prepared. Using it as a building block, a one-dimensional chain compound, {[Fe-II(Tpms)(CN)(3)][Mn-II(H2O)(2)( DMF)(2)]}. DMF (3), has been synthesized and structurally characterized. The magnetic properties of 3 correspond to a ferromagnetic chain with weak long-range superexchanged magnetic interaction between the high-spin manganese(II) ions. (c) 2005 Elsevier B.V.
