(Ph4P)2[ReCl5(tcm)] - a new precursor of molecular magnets
New complex of composition (PPh4)2[ReCl5(tcm)] have been obtained and characterized by IR, UV-Vis spectroscopies and magnetic measurements. The rhenium atom is six coordinate with five chloride atoms and one tcm group. The compound contains tcm- in menodendate function coordinated to metal via the N-atom. The temperature dependence of magnetic susceptibility measured over the range 1.73-300 K showed the presence of a very weak antiferromagnetic interaction ( zJ=-0.78 cm-1) between the rhenium atoms.
