Synthesis, Crystal Structure and Properties of a Di‐μ‐phenoxo Dinuclear Nickel(II) Complex with a Tridentate Schiff Base Ligand

A new di‐μ‐phenoxo dinuclear nickel(II) complex, [Ni2(Hsae)2(CH3COO)2(H2O)2] (H2sae = salicylidene‐2‐ethanolamine), has been synthesized and characterized by molar conductances, electronic spectra, IR spectra and cyclic voltammetry. The X‐ray structure analysis of this novel nickel(II) complex (C22H30N2O10Ni2, monoclinic, P2(1)/n, a = 9.554(20) Å, b = 17.65(4) Å, c = 15.10(3) Å, β = 95.04(4)°, Z = 4) reveals that the complex is composed of a dinuclear unit and the two nickel(II) ions are doubly bridged by the phenoxo group. Each nickel(II) ion adopts a distorted octahedral structure in which the NO3 donor set coming from the Schiff base ligand forms an equatorial plane, and the remaining axial positions are occupied by the O2 donor set of acetate and water.
