Cher François,

I'll draw the formula of tetrathionic acid, but if it gets distorted on
transmission I'll give you as well a recipe how to draw it yourself.

HO-S-S-S-S-OH --> (O-S-S-S-S-O)=
   | | | |
   O O O O

Take two molecules of sulfuric acid and chop off one OH from each one:

HO3S + SO3H

Now join the two S atoms with -S-S-, you get the tetrathionic acid; remove
the protons, you get your ion. Charges are delocalized.

Voila

Jacob
