A2M(CO3)2 was reported to be formed usually between alkali metal and alkaline earth metals. Considering structure of A2M(CO3)2 variation depending on metal ions, its formation may occurred over a wider range metal ions including transition metal. In reality, transition metal based double carbonate was rare. We observed double carbonate between Na and Cd (to be denoted Z), while encouraging CdO to absorb CO2. Several syntheses were tried for obtaining pure state Z by varying some conditions under 1 atm CO2. This result gives us an insight that Z is metastable compound more thermodynamically unstable than CdCO3. By replacing M of A2M(CO3)2 in Nyerereite (Na1.33K0.67Ca(CO3)2) and Fairchildite (K2Ca(CO3)2) with Cd, we conjectured that Z has similar to those things. Despite of a few mismatchings, Z was found to have a chemical formula Na2Cd(CO3)2.
