| Abstract: A nickel(Ⅱ) cluster, {[Ni(L)H2O]2(OAc)2Ni}·2EtOH, has been synthesized by the means of the complexation of nickel(Ⅱ) acetate tetrahydrate with a new Salen-type bisoxime ligand (H2L, 4,4′-dimethoxy-2,2′-[ethylenedioxybis(nitrilo-methylidyne)]diphenol). The crystal structure shows that the hexacoodinated terminal nickel(Ⅱ) ions lie in the N2O2 coordination sphere of Salen-type bisoxime ligands, quadruple μ-phenoxo oxygen atoms from two [NiL] chelates coordinated to the central nickel(Ⅱ) ion, and the two acetate anions coordinated to three nickel(Ⅱ) ions through Ni-O-C-O-Ni bridges. Thus, all the three nickel atoms of the cluster have distorted octahedral geometries. CCDC: 736762. |
