Complexes Cl-RuⅡ(dppe)2(Fe Cl4)·2CH2Cl2(2) and Br-RuII(dppe)2(Fe Br4)·2CH2Cl2(3) were prepared by the reaction of trans-RuII(dppe)2Cl2(1) with FeX 3(X = Cl, Br). More interestingly, the central Ru atoms of RuII(dppe)-based complexes(2 and 3) define a tetragonal pyramid with five-coordination. The temperature dependence magnetic susceptibilities indicate that the xMT values of complexes 2 and 3 are almost constant at 50~300 K, and the xMT values sharply decrease with further decreasing the temperature at low temperature due to the zero-field splitting(ZFS) of high spin Fe(III) ions.
