| 摘 要： | 采用TpFeⅢ(CN)3]-作为构筑基块，合成并表征了一个氰基桥联双核配合物(Tp)FeⅢ(CN)3CuⅡ(bpy)2]ClO4·CH3OH (1)。对化合物1进行了晶体结构分析，其晶胞参数为a=0.904 26(5) nm，b=1.352 56(7) nm，c=1.556 02(8) nm，α=106.08(1)°，β=95.79(1)°，γ=91.01(1)°，P1空间群。在这个化合物中，TpFeⅢ(CN)3]通过其中1个氰基与Cu(bpy)2]2+桥联，而另外2个氰基未参与配位。磁性研究表明，在化合物1中，Cu(Ⅱ)与Fe(Ⅲ)离子之间表现为铁磁相互作用。用哈密顿函数H=-2JSFeSCu对其χMT-T曲线进行了拟合，得到1的朗德因子g=2.34和交换常数J=5.52 cm-1。

| Abstract: | By using a tricyanometalate precursor TpFeⅢ(CN)3]- (Tp=hydrotris (pyrazolyl)borate)as a structural building block, a new cyanide-bridged dinuclear complex, (Tp)FeⅢ(CN)3Cu Ⅱ(bpy)2]ClO4·CH3OH (1) (bpy=2, 2-bipyridine), has been prepared and characterized. It crystallizes in triclinic space group P1, with a=0.904 26(5)nm, b=1.352 56(7) nm, c=1.556 02(8) nm, α=106.08(1)°,β=95.79(1)°, γ=91.01(1)°. In the complex, TpFe(CN)3]-acts as a monodentate ligand toward a central Cu(bpy)2]2+ core through one of its three cyanide groups, the other two cyanides remaining terminal. Magnetic studies for complex 1 show ferromagnetic coupling between the Cu(Ⅱ)and Fe(Ⅲ) ions, giving an S=1 ground state. The best-fit forχMT vs T with an Hamiltonian H=-2JSFeScu leads to the parameters g=2.34, J=5.52 cm-1 for 1. CCDC: 622244. |
