Uranyl carbonate refers to the inorganic compound with the formula UO2CO3.

Like most uranyl salts, the compound is a polymeric, each uranium(VI) center being bonded to eight O atoms.

[1] Hydrolysis products of rutherfordine are also found in both the mineral and organic fractions of coal and its fly ash and is the main component of uranium in mine tailing seepage water.

[2] Many uranyl carbonates exist, rutherfordine being the simplest stoichiometry.

Most uranyl carbonates additional components including water and diverse anions and cations.
