Answer:

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

Explanation:

The central carbon atom is surrounded by #3xxsigma# bonds, and a #C-O# #pi# bond, that is conceived to be delocalized around the oxygen centres:

#O=C(-O)_2^(-)#

Electron counting means that we have to distribute 24 electrons around the oxygens and carbon, and this gives a trigonal plane around the central carbon.
