By reaction of Zn4O(O2CNMe2)(6) (1) with [NH2Me2][O2CNMe2] in toluene as medium, the homoleptic zinc compound [Zn(O2CNMe2)(2)] (2) was obtained, which reverted back to the tetranuclear mu-oxo derivative by controlled hydrolysis. The reaction of ZnO in MeCN with an excess of [NH2Me2][O2CNMe2] in concentrated solution produced high yields of [Zn(O2CNMe2)(2)] (2) or [NH2Me2][Zn-2(O2CNMe2)(5)] center dot xMeCN, 3 center dot xMeCN, x = 1 or 2, depending on the experimental conditions.

[Problem] To provide a new way for fixing carbon dioxide under mild conditions and with high efficiency.
[Solution] The material for carbon dioxide fixation according to the present invention contains a metal ion donor and an amine as a precursor of a bridging ligand. The amine is configured to react with a gaseous carbon dioxide to form the bridging ligand having at least one carbamate anion moiety. The bridging ligand is configured to react with the metal ion donor to form a coordination polymer in which a plurality of the metal ions is linked by the bridging ligand.
