I am trying to find the structures of thiosulfate, Dithionate & Tetrathionate Ions but I am not getting an exact answer. Please help.




Here you go...


[Thiosulfate](http://en.wikipedia.org/wiki/Thiosulfate) $\ce{[S2O3]^{-2}}$

There ia a negative charge on the apical sulfur and another negative charge distributed across the 3 oxygens by resonance


[Dithionate](http://en.wikipedia.org/wiki/Dithionate) $\ce{[S2O6]^{-2}}$

There is one negative charge distributed by resonance over each group of 3 oxygens.


[Dithionite](http://en.wikipedia.org/wiki/Dithionite) $\ce{[S2O4]^{-2}}$

There is one negative charge distributed by resonance over each group of 2 oxygens.


[Tetrathionate](http://en.wikipedia.org/wiki/Tetrathionate) $\ce{[S4O6]^{-2}}$
