摘　　要：标题化合物是由 [Ni(bipy) 3 ]2 +络合物与FeCl2 在MeOH、DMF及异丙醇混合溶剂中直接反应得到的 ,它可溶于水、乙醇和DMF等极性溶剂 ,不溶于乙醚 .X -射线结晶学研究表明 :标题物中含有 [Ni(bipy) 3 ]2 +和 [(μ -oxo)Fe2 Cl6]2 - 离子 ,晶胞参数 :单斜 ,P2 1 c,a=0 .970 9nm ,b =2 .6 40 9nm ,c =1.40 14nm ,β =10 0 .2 4° ,V =3.5 36nm3 ,Z =4,Dc =1.6 30g cm3 ,F (0 0 0 ) =1744 ,μ =1.82 4nm- 1 .化学实验式为 :C3 0 H2 4Cl6Fe2 N6NiO .分子量 Mr=86 7.6 6 .对标题物进行X -荧光元素分析、红外、可见吸收光谱和磁化率的研究 .The title compound is obtained by the reaction of the [Ni(bipy) 3] 2- and FeCl 2 in the MeOH, DMF and isopropanol mixed solvents. It is soluble in EtOH, DMF and H 2O such as polar solvents et al except ether. The studies of XRD show that the title compound is composed of [Ni(bipy) 3] 2+ and [(μ-oxo)Fe 2Cl 6] 2- ions. The crystal cell parameter monoclinic. P2 1/c, a=0.970?9?nm, b=2.640?9?nm, c=1.401?4?nm, β=100.24°, V=3.536?nm 3, Z=4, D\-c=1.630?g/cm\+3, F(000)=1?744, μ=1.824?nm -1. Its empirical formula is C 30H 24Cl\-6Fe\-2NiO, Mr=867.66. We perform the research on XRF, IR, visible absorption spectra and magnetic properties.
