采用“一锅煮”方法, 在金属Ni(II)离子作用下, 以2-乙酰吡啶和1,2-丙二胺物质的量比为2∶1进行反应, 得到了一种新的闭环单Schiff碱N4四齿配体的配合物[C17H20N4Ni(H2O)Cl]2Cl2•(CH3OH). 配合物的晶体结构测定表明, 其配位单元为N桥连的双核配合物, 配位单元间再通过氢键连接成一维链状结构.

A novel binuclear nickel(II) complex [C17H20N4Ni(H2O)Cl]2Cl2•(CH3OH) with organic ligands of 2-acetylpyridine and 1,2-propylenediamine has been one-pot synthesized and characterized by means of elemental analysis, IR and single crystal X-ray diffraction. The structure analysis reveals that each nickel(II) ion is coordinated in a distorted octahedral (NiN4OCl) fashion consisting of four nitrogen atoms from pyridine and 1,2-propylenediamine, respectively, one water molecule and one chloride ion. There are intermolecular hydrogen bonds, through which a one dimensional chain structure is formed. With the template action of nickel(II), a novel Sciff base ligand with four N donor atoms was obtained.
