Carbon has valency 4. To attain noble gas configuration it need to gain or lose 4 electrons so that it would form ionic compound.

1. If it gain 4 electrons it would be difficult for nucleus to hold 6 protons on to 10 electrons.

2. If it lose 4 electrons it would require lot of energy to lose 4 electrons from nucleus holding 6 protons on to just 2 electrons.

Thus carbon doesnt form ionic compounds.
