Resonance structure effect on molecular shape

ClO2+ has 4 different resonance structures so I am wondering if each structure would warrant a different molecular shape.

Thanks

Can you clarify, is the molecular formula you're asking about ClO2+ ?

No. Because the resonance structures include moving around double bonds, and double bonds are counted as one bond pair in the VSEPR model, then the molecular shape of each should be the same.

You also have to keep in mind that the actual structure of the compound is a hybrid of all the resonance structures. So one resonance structure wouldn't have a greater effect on the shape or anything. As stated above, since resonance structures is basically shifting double bonds around, the bonds are all the same anyway when determining shape.
