Synthesis and Properties of Nickel (Ⅱ) Complex Containing Bis (Diphenylphosphino ) Ethane
【摘要】 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)Cl2],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p21/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=2402.5A3, Z=4, F(000)=1088, Dcalc=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.
【Abstract】 Mononuclear nickel (Ⅱ) complex [ Ni (dppe) Cl2] (dppe = Ph2PCH2CH2PPh2) has been synthesized by replacement reaction in CHCl3 and characterized by specific elemental analyses, molecular weight determination, IR spectra, XPS, conductivity and X-ray single crystal analysis. The crystal is monoclinic, space group P21/ c, a = 11. 429(2), 6 = 13. 346(2), c = 15.953(7) A; β = 99. 13(3)°, V= 2402.5A3, Z =4, F(000) = 1088, Dcalc= 1. 460g.cm-3, μ= 11. 782cm-1, R = 0. 04470, Rw = 0. 05352. The results show that dppe coordinates as bidentate ligand to the Ni (Ⅱ) atoms, and Cl anion behaves as a monodentate ligand in the prepared complex.
