Based on a alacritous search I have yet to find solid evidence that such a compound is possible.
Tin(IV) carbonate
The chemical formula of copper (II) carbonate is CuCO3.
The chemical formula for Mercury II Carbonate is HgCO3.
The formula for germanium(II) carbonate is GeCO3.
Sn(CLO3)2 Tin (II) has a positive 2 charge and Chlorate has a (-1) charge so you need to cholrates to one Tin.
The formula for the compounds: Chromium (VI) Phosphate; Vanadium (IV) Carbonate; Tin (II) Nitrite?
Tin(IV) carbonate
It is ZrCO3.
The chemical formula of copper (II) carbonate is CuCO3.
The chemical formula for Mercury II Carbonate is HgCO3.
The formula of iron II hydroxide is Fe (OH) 2
The formula for germanium(II) carbonate is GeCO3.
The chemical formula for tin(II) sulfite is SnSO3.
The formula name of Ni2(CO3)2 is nickel(II) carbonate.
Sn (Tin) and C (Carbon) don't normally occur together. The closest reference I could find was to "Tin-Doped Carbon Clusters" in a chemistry journal.
Sn(CLO3)2 Tin (II) has a positive 2 charge and Chlorate has a (-1) charge so you need to cholrates to one Tin.
Tin has two oxidation states (II and IV), and exhibits approximately equal stability in both its II and IV oxidation state. The chemical formula Tin (II) Iodide is SnI2. The chemical formula for Tin (IV) Iodide is SnI4.
