合成了一种含有螯合双肟配体2,2'-[(1,3-亚丙基)二氧双(氮次甲基)]二萘酚(H2L)的三核镍(Ⅱ)簇合{[NiL(THF)]2(OAO)2Ni}·THF,并通过红外光谱、差热-热重进行了结构表征,同时测定了它的晶体结构.该簇合物晶体属三斜晶系,空间群为P1.在镍(Ⅱ)簇合物中,含有2个配体单元(提供N2O2给予体)、2个乙酸根离子和2个配位的四氢呋喃分子,共同围绕镍(Ⅱ)离子形成了3个稍微扭曲的八面体配位几何体.

A novel trinuclear nickel(Ⅱ) cluster {[NiL(THF)]2(OAc)2Ni}·THF with chelating bisoxime ligand 2,2'-[(1,3-propylene)dioxybis(nitrilomethylidyne)]dinaphthol (H2L) was synthesized and structurally characterized by IR spectra, TG-DTA and X-ray single crystal structure analysis. The cluster crystallizes in the triclinic system, space group P1, with unit cell parameters a=0.969 78(17) nm, b=1.367 7(2) nm, c=2.422 4(3) nm, α=76.185(2)°,β=86.921(3)°,γ=77.865(2)° and V=3.0502(8) nm3, Z=2, R1=0.058 0, wR2=0.125 2. In the Ni(Ⅱ) cluster, there are two ligand moieties (which provide N2O2 donors), two acetate ions and two coordinated THF molecules, which result in the formation of three slightly distorted octahedral geometries around the Ni(Ⅱ) ions.
