What is the oxidation state of oxygen in chromium ionic bonds?
Since ionic bonds between ions are mostly "exchanging superscripts for subscripts", we can already glean that the oxidation state for chromium is +3 . (2) Long answer: Most often than not, the oxidation state of oxygen is -2 (mainly due to it being a member of Group 6 in the periodic table and it being electronegative).

Probably, you mean the oxidation state of vanadium in that complex anion. Well, it should be -1. Actually, as regards the six dative bonds made by the CO molecules with the vanadium ion, the couple of electrons each CO molecule employs for the purpose remains closer to the carbon atom, which is more electronegative than vanadium, whose oxidation state remains unaffected. The extra electron that provides the ion under examination with its negative charge can be thought of as localized on the V atom, which has some half-filled orbitals where the extra electron could be placed. As a conclusion, t
