在氯访中通过取代反应制备了含双二苯基膦乙烷（ｄｐｐｅ）的镍配合物［Ｎｉ（ｄｐｐｅ）Ｃｌ_２］，并通过元素分析、热分析、红外光谱、核磁、电导测定、光电子能谱及Ｘ－射线单晶分析表征了配合物的结构和性质，晶体属于单斜品系，空间群为ｐ２_１／ｃ。晶胞参数如下：ａ＝１１．４２９（２），ｂ＝１３．３４６（２），ｃ二１５．９５３（７）Ａ；β＝９９．１３（３）°，Ｖ＝２４０２．５Ａ~３， Ｚ＝４， Ｆ（０００）＝１０８８， Ｄ_（ｃａｌｃ）＝１４６０９· ｃｍ~（－３）， ｐ＝１１．７８２ｃｍ~（－１）， Ｒ＝０．０４４７０， Ｒｗ＝０．０５３５２。分析结果表明，配合物中双二苯基膦乙烷属双齿配体，氯离子是单齿配体．
Nickel complex [Ni (dppe) Cl_2] with diphenylphosphine ethane (dppe) was prepared by substitution reaction in the presence of chlorine. The results of elemental analysis, thermal analysis, FTIR, NMR, The structures and properties of the complexes were characterized by X-ray single crystal and X-ray crystallography. The crystal belongs to the monoclinic strain with space group p2_1 / c. The unit cell parameters are as follows: a = 11.429 (2), b = 13.346 (2), c = 15.953 (7) A; , Z = 4, F (000) = 1088, D calc = 14609 cm -3, p = 11.782 cm -1, R = 0.04470, Rw = 0.05352. The analysis results show that the bis (diphenylphosphino ethane) bidentate ligand and the chloride ion are monodentate ligands.
