If this compound existed it would be called chromium heptoxide. This would imply an impossibly high oxidation number for chromium.
Chromium forms a number of oxides including Cr2O3 and a chromium(VI) oxide, chromium oxide peroxide.

What is the formula for tin (IV) chromate?
Sn(CrO4)2 Tin 4 means that the tin is a cation with a +4 charge. Chromate is a polyatomic ion with the formula (CrO4)-2. Since the tin ion has a +4 charge in this case, and the chromate ion has a -2 charge, there is a 1:2 ratio of tin ions to chromate ions.
How many ions in silver chromate?
Two types: silver (Ag+) and chromate (CrO4-2) And within the formula (Ag2CrO4) there are two silver ions and one chromate ion for a total of three ions.
Is Pb(CrO4)2 a molecular compound?
No. It is an ionic compound composed of the lead IV cation (Pb4+) and the chromate anion (CrO4)2-.Pb4+ + 2(CrO4)2- --> Pb(CrO4)2
