WebMay 11, 2015 · A recent paper by S. Shaik reports that a quadruple bond exists in C 2. And hence though the actual molecule has been found, its chemistry is still being studied. Actually, the electrons not in the bonding orbitals are in non-bonding orbitals, not anti-bonding orbitals. Diatomic carbon does not have a quadruple bond but a double bond. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch8/mo.html
