Nickel(II) carbonate is the chemical compound with the formula NiCO3. It is a pale green polymeric solid consisting of Ni2+ centers linked to CO32- centers. NiCO3 does not actually dissolve in any solvent but it is readily decomposed by aqueous acids to give solutions containing the ion [Ni(H2O)6]2+. Pyrolysis of NiCO3 gives NiO:
- NiCO3 → NiO + CO2
