Carbon dioxide is an attractive feedstock for many chemical processes due to its low cost, low toxicity, and abundance. The complexity of metal oxides conventionally used to fix CO2 makes them difficult to study. The molybdate dianion is a low-cost and readily available alternative with a simpler structure. However, commercially available forms of this compound are insoluble in most organic solvents and does not react with CO2 under aqueous conditions. This invention describes a novel molybdate complex that readily reacts with CO2 at room temperature.
