以2,6-二[N-(1’-甲基-2’-羟乙基)氨甲酰基]吡啶为配体与Cd(NO3)2·4H2O反应,合成了一个单核镉(Ⅱ)配合物,通过元素分析、红外光谱、紫外光谱及X-射线单晶衍射法对其结构进行了表征。结构分析表明,该配合物属三斜晶系,P-1空间群,晶胞参数a=0.938 22(18)nm,b=0.944 74(19)nm,c=1.299 9(2)nm,α=105.687(7)°,β=95.154(6)°,γ=101.755(7)°。V=1.073 1(4)nm3,Z=2,Dc=1.757 g/cm3,μ=1.089 mm-1,F(000)=576.0。配合物的中心镉(Ⅱ)离子配位数为8,处于扭曲的四方反棱柱构型。考察了配体对Cd(Ⅱ)离子的液膜传输性,结果表明2,6-二[N-(1’-甲基-2’-羟乙基)氨甲酰基]吡啶可作为良好的Cd2+离子载体。
A novel mononuclear cadmium (Ⅱ) complex was synthesized by the reaction of 2,6-bis [N- (1’-methyl-2’-hydroxyethyl) carbamoyl] pyridine with Cd (NO3) Its structure was characterized by elemental analysis, IR, UV and X-ray single crystal diffraction. The structure analysis shows that the complex belongs to the triclinic system with P-1 space group, with a = 0.938 22 (18) nm, b = 0.944 74 (19) nm and c = 1.299 9 = 105.687 (7) °, β = 95.154 (6) °, γ = 101.755 (7) °. V = 1.073 1 (4) nm3, Z = 2, Dc = 1.757 g / cm3, μ = 1.089 mm-1 and F (000) = 576.0. The coordination number of cadmium (Ⅱ) ion in the center of the complex is 8, which is in a twisted tetragonal antiprism configuration. The results showed that 2,6-bis [N- (1’-methyl-2’-hydroxyethyl) carbamoyl] pyridine could be used as a good Cd2 + Ionophore
