Abstract: 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=3.050 2(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.
