inorganic chemistry - How to prepare iron(II) carbonate from iron(III) chloride?


Now, this is an awkward reaction first of all. I know how to prepare $\ce{Fe2(CO3)3}$ from $\ce{FeCl3}$:



$$\ce{2FeCl3 + 3Na2CO3 -> 6NaCl + Fe2(CO3)3}$$


But the question is asking for $\ce{FeCO3}$. It seems to be an impossible task but since this was asked in a public examination, does anybody know how to prepare $\ce{FeCO3}$ from $\ce{FeCl3}$ (in one, two or three reactions)?
