#/_O-S-O=120^@#.

Explanation:

Given the normal assumptions of VESPER, we have #4xx6=24# #"valence electrons"# to distribute around 4 centres.

A Lewis structure of #O=S^(2+)(-O^-)_2# is commonly invoked, even tho #S(=O)_3# is structurally identical. Can you apportion the 24 valence electrons in the given #O=S^(2+)(-O^-)_2#?
