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.
