Abstract

The fixation of CO₂ at ambient temperature has been achieved by the reaction of Ni(cod)₂ and TMEDA in CO₂ saturated THF that yields a novel hexanuclear nickel(II) μ₃-carbonato bridged complex [Ni₆(μ₃-CO₃)₄(TMEDA)₆(H₂O)₁₂](OH)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.
