A trinuclear Ni(II) cluster with two significantly different configurations in the solid state.

A chelating bisoxime ligand, 2,2'-[(1,3-propylene)dioxybis(nitrilomethylidyne)]dinaphthol (H2L), and its corresponding Ni(II) cluster {[NiL(H2O)]2(OAc)2Ni} · 0.5MeOH · 0.5CH3CN · H2O (1) have been synthesized and characterized by elemental analyses, TG-DTA, IR, 1H NMR and X-ray diffraction methods. The Ni(II) cluster is monoclinic, space group P2(1)/c with cell dimensions a = 9.400(2), b = 24.530(4), c = 25.350(3) Å and β = 92.823(3)°. In the Ni(II) cluster, there are two ligand moieties (which provide N2O2 donors), two acetate ions and two water molecules, which result in three slightly distorted octahedral geometries around the Ni(II) ions.
