The first line of the Wikipedia article on Organic Chemistry says:
"Organic chemistry is a subdiscipline of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbon in covalent bonding."
This suggests that carbon compounds with no covalent bonds are excluded but what are these compounds? I am aware that other types of bonds may occur and be important but, even when they do, the compound still seems to be regarded as organic.
What is an example of a carbon compound excluded by the clause "which contain carbon in covalent bonding"?
