The reduction of the relatively inert carbon–oxygen bonds of CO<sub>2</sub> to access useful CO<sub>2</sub>-derived organic products is one of the most important fundamental challenges in synthetic chemistry. Facilitating this bond-cleavage using earth-abundant, non-toxic main group elements (MGEs) is especially arduous because of the difficulty in achieving strong inner-sphere interactions between CO<sub>2</sub> and the MGE. Herein we report the first successful chemical reduction of CO<sub>2</sub> at room temperature by alkali metals, promoted by a cyclic(alkyl)(amino) carbene (CAAC). One-electron reduction of CAAC-CO<sub>2</sub> adduct (<b>1</b>) with lithium, sodium or potassium metal yields stable monoanionic radicals clusters [M(CAAC–CO<sub>2</sub>)]<sub>n</sub>(M = Li, Na, K, <b> 2</b>-<b>4</b>) and two-electron alkali metal reduction affords open-shell, dianionic clusters of the general formula [M<sub>2</sub>(CAAC–CO<sub>2</sub>)]<sub>n </sub>(<b>5</b>-<b>8</b>). It is notable that these crystalline clusters of reduced CO<sub>2</sub> may also be isolated via the “one-pot” reaction of free CO<sub>2</sub> with free CAAC followed by the addition of alkali metals – a reductive process which does not occur in the absence of carbene. Each of the products <b>2</b>-<b>8</b> were investigated using a combination of experimental and theoretical methods.<br>

The title compound was isolated from the treatment of Tp*Sn(Cl)2Bu (1) with a large excess of sodium hydroxide in a mixture of acetone-water at room temperature. [(Me2CO)3(NaTp*)2] (2) crystallizes at 4 °C as prismatic colorless crystals, in the monoclinic space group P21/c with Z = 4, a = 12.2837(6), b = 24.3197(12), c = 16.9547(8) Å, β = 110.017(1)°, and V = 4759.0(4) Å3. The X-ray crystallographic analysis revealed a dinuclear unit in which two Tp*Na moieties are held together by three bridging acetone molecules acting as oxygen-based donors.
