Di-μ-phenolato-μ-aqua-bridged Dinuclear Nickel(II) Complex with N,N′-Disalicylidene-2,2′-(ethylenedioxy)bis(ethylamine)

摘要

>A dinuclear nickel(II) complex with N,N′-disalicylidene-2,2′-(ethylenedioxy)bis(ethylamine) (H₂dee), [Ni₂(dee)₂(μ-H₂O)]·2EtOH (1), was synthesized. The crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. The complex crystallizes in the monoclinic space group C2/c with a = 18.321(8), b = 13.543(6), c = 18.649(9)?, β = 108.372(8)°, V = 4391(3)?3, D_calcd = 1.416 g/cm3, Z = 4. The R₁ [I 2σ(I)] and wR2 (all data) values are 0.0347 and 0.0736, respectively, for all 5014 independent reflections. The complex is composed of a dinuclear molecule with di-μ-phenolato-bridges of dee2? and the μ-aqua-bridge, and crystal ethanol molecules. The electronic spectral feature is consistent with the octahedral geometry of the nickel(II) ions.
