| 摘要: 合成了配合物Ni(Aim)4(SCN)2(Aim=1-烯丙基-1H-咪唑)，并采用X射线单晶衍射仪测定了其晶体结构。配合物属三斜晶系，P1 空间群，晶胞参数为：a=0.883 90(18) nm，b=0.953 90(19) nm，c=1.051 5(2) nm，α=70.22(3)°，β=65.29(3)°，γ=86.66(3)°，V=0.754 3(3) nm3，Z=2。在配合物中，每个Ni(Ⅱ)原子分别和来自4个Aim配体的4个氮原子、2个异硫氰酸根的2个氮原子配位，形成八面体配位结构。在晶体中，分子通过C-H…N分子间弱相互作用沿a轴形成一维锯齿结构。电化学研究显示配合物中Ni2+/Ni对的氧化还原是一个准可逆过程。 |

| Abstract: The title complex Ni(Aim)4(SCN)2(Aim=1-allyl-1H-imidazole) has been synthesis and structurally characterized by X-ray diffraction single-crystal structure analysis. The complex crystallizes in triclinic system, P1 space group with the cell parameters of a=0.883 90(18) nm , b=0.953 90(19) nm, c=1.051 5(2) nm, α=70.22(3)°, β=65.29(3)°, γ=86.66(3)°, V=0.754 3(3) nm3 and Z=2. In the structure of the complex, each Ni(Ⅱ) ion is coordinated by four N atoms from four Aim molecules and two N atoms from a pair of monodentate isothiocyanic groups. in a octahedral coordination geometry. The C-H…N weak interactions link the molecules into a 1D zigzag chain along the a axis. The electrochemical studies reveal that redox of Ni2+/Ni in the complex is a quasi-reversible process.
