目的研究葡萄糖胺和麦芽糖胺-过渡金属配合物的结构,为其应用奠定基础,合成及表征了4个葡萄糖胺和麦芽糖胺-过渡金属配合物。方法以葡萄糖和麦芽糖为原料,将合成的双葡萄糖丙二胺配体及双麦芽糖丙二胺配体分别与过渡金属Cu(II)、Ni(II)形成配合物。结果以33.9%~73.8%的产率制备了4个葡萄糖胺和麦芽糖胺-过渡金属配合物,并通过紫外、红外、元素分析、摩尔电导等数据推测出了配合物的结构式。结论过渡离子与配体的摩尔比为1∶2,Cu(II)配合物含有两种配位构型分别为不规则四边形和三角双锥,而Ni(II)配合物的构型为2分子水参与的八面体构型。
Aim To study the structure of glucosamine and maltosamine-transition metal complexes, and to lay the foundation for its application. Four glucosamines and maltosamine-transition metal complexes were synthesized and characterized. Methods Glucose and maltose were used as raw materials to synthesize the complexes of propylene glycol dimer and maltose propylenediamine respectively with transition metal Cu (II) and Ni (II). Results Four glucosamine and maltosamine - transition metal complexes were prepared in the yield of 33.9% ~ 73.8%. The structures of the complexes were deduced by UV, IR, elemental analysis and molar conductance. Conclusion The molar ratio of transitional ions to ligand is 1: 2. The Cu (II) complexes contain two kinds of coordination structures: irregular tetragon and triangular double cone, respectively. The configuration of Ni (II) Octahedral configuration with water involved.
