摘　　要：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.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）.
