It is also incorrect. There are plenty of carbonyls in which the
metal is in a positive oxidation state -- start with [Re(CO)6]+.
: check your textbook under bonding and
: how/where ligands attach to the metallic center atoms. also note the
: charge location on CO.
I think that a more fruitful way to start would be to ask which interaction
dominates the metal-CO bond: the sigma bond or the pi bond? What
characteristics of the metal are likely to increase the strength of
that interaction?
