How many atoms in CoO3?

The formula CoO3 has 4 atoms: 1 cobalt and three oxygen. That said, I'm doubtful that that compound actually exists. CoO and Co3O4 both definitely do, Co2O3 is probable but less certain, but the oxidation states involved in those are all reasonable ones for cobalt; +6 would be unusual to say the least.
