inorganic chemistry - What are the resonance structures for chlorite anion?


What are the possible resonance structures for ClOX2X? Assigning one double bond to the structure makes for formal charges of O(1)Cl(0)=O(0)O(1)=Cl(0)O(1). It appears that the same set of formal charges can be achieved with two double bonds (expanding the octet on Cl to 12 electron capacity, using the d orbital). That is, O(0)=Cl(1)=O(0).


Is this feasible, and if not, why not?
