根据文献方法合成了金属配合物[Ni(HL)]Cl2•2H2O (HL＝1-[(2-氨乙基)氨基]-2-氨基-1,2-二脱氧-D-葡萄糖), 并用重结晶方法得到了适于X射线衍射的Ni(II)配合物的单晶. 通过对其进行元素分析、红外、紫外光谱及X射线衍射分析, 表明其为畸变的八面体构型. 最后研究了配合物对对硝基苯吡啶甲酸酯(PNPP)催化水解活性.

One complex [Ni(HL)]Cl2•2H2O (HL＝1-[(2-aminoethyl)amino]-2-amino-1,2-dideoxy-D-glu- cose) has been synthesized using previously published procedures, and the single crystal of [Ni(HL)]Cl2• 2H2O was got. It was characterized by elemental analysis, IR, UV spectra and X-ray diffraction analysis, showing that the complex was in distorted octahedron configuration. Then the catalytic activity of the complex on hydrolysis of p-nitrophenyl picolinate (PNPP) in buffer solution was studied as well.

Key words: metal-saccharide complex, synthesis, crystal structure
