摘　　要：用2,6-吡啶二甲醛和对甲苯胺反应,合成二亚胺吡啶类配体L(2,6-二[1-(4-甲基苯基)亚胺基]吡啶),采用室温挥发法制备配体L与过渡金属Fe(Ⅱ)的配合物,并对所合成的吡啶希夫碱铁配合物进行了红外光谱、元素分析等测试,用X-射线单晶衍射技术确定了配合物的晶体结构。结果表明:铁配合物属于三斜晶系,其空间群为P-1,中心铁离子为五配位,位于配体的三个氮原子和两个游离的氯离子组成的变形的的三角双锥的中心,同时通过分子间氢键可以连接成一维链状结构。2,6-bis（6-methylquinolin-2-yl）-Pyri-dine ligand was prepared from 2,6-bipyridine-2-formaldehyde and p-ami-toluene. Under the room temperature, metal complexes Fe L were synthesized by the method of solvent evaporation, and Fe L was also characterized by IR, Elements analysis and X-ray single crystal diffraction. The results reveal that Fe L belongs to triclinic system and p-1 group. In the complex, the center metal is tridentately chelated by ligand and further coordinated by two chlorine atoms, resulting in distorted trigonal-bipyramidal geometry. In addition, crystal packing in complex is stabilized by C-H？？？Cl inter-molecular hydrogen bond, which link the mononuclear complex to the 1D chain.
