The fixation of CO(2) at ambient temperature has been achieved by the reaction of Ni(cod)(2) and TMEDA in CO(2) saturated THF that yields a novel hexanuclear nickel(II) mu(3)-carbonato bridged complex Ni(6)(mu(3)-CO(3))(4)(TMEDA)(6)(H(2)O)(12)(4) in 59% yield. The complex was characterised by MS analysis and the structure corroborated by single-crystal X-ray crystallography. The complex exhibits a rare carbonato binding mode for Ni(II) complexes and moderately strong antiferromagnetic interactions.
在室温下，通过 Ni(cod)(2)和 TMEDA 在 CO(2)饱和 THF 中的反应实现了 CO(2)的固定，生成了一种新型的六核镍(II)μ(3)-桥连碳酸根的配合物Ni(6)(μ(3)-CO(3))(4)(TMEDA)(6)(H(2)O)(12)(4)，产率为 59%。该配合物通过 MS 分析进行了表征，并通过单晶 X 射线晶体学进行了结构确证。该配合物表现出了 Ni(II)配合物中罕见的碳酸根配位模式和中等强度的反铁磁相互作用。
