# Has a carbon compound ever been found having an ionic bond?

Though it is highly unlikely, has any carbon compound been found to make an ionic bond and to exhibit ionic properties?

Why unlikely? Ionic compounds of carbon have been known for ages. There are ionic carbides ($\ce{Al4C3}$, $\ce{CaC2}$, etc.), graphite intercalation compounds like $\ce{KC8}$, ionic derivatives of fullerenes and more.

Come to think of it, common $\ce{CaCO3}$ is certainly ionic and at the same time a compound of carbon, but this is most likely not what you want.

There is also the classical case of the aromatic carbocations and carbanions; examples include tropylium bromide,

and sodium cyclopentadienide, which is used for preparing "sandwich compounds", among other uses.

Perhaps what you meant to ask was

Are there any known organic compounds with ionic bonds?

Organic salts would be examples of organic compounds with ionic bonds. Here is a list of organic salts.
