| Abstract: A novel chelating bisoxime ligand, 4,4′-dichloro-2,2′-[(1,3-propylene)dioxybis(nitrilomethylidyne)]diphenol (H2L), and its corresponding trinuclear Ni(Ⅱ) cluster {[NiL(C2H5OH)]2(OAc)2Ni}·C2H5OH (1) have been synthesized and characterized by elemental analyses, IR, 1H NMR and X-ray singel crystal diffraction method. The crystal of the Ni(Ⅱ) cluster belongs to monoclinic, space group P21/n with cell dimensions a=1.336 53(18) nm, b=1.341 64(18) nm, c=1.549 8(2) nm, β=106.841(2)°, and V=2.659 8(6) nm3, Z=2, R1=0.051 6, wR2=0.157 4. In the Ni(Ⅱ) cluster, there are three nickel(Ⅱ) atoms, two ligand moieties (which provide N2O2 donors), two acetate ions and two coordinated ethanol molecules, which result in the formation of a slightly distorted octahedral coordination geometry around each Ni(Ⅱ) ion respectively.
