This content is a preprint and has not undergone peer review at the time of posting.

Abstract

The global minima of thirteen combinations of atoms with formula CE3M3+ (E=S-Te and M=Li-Cs) adopt a planar structure with carbon covalently bonded to three chalcogens and ionically bonded to the three alkali-metals to stabilize the first global minima structures containing planar hexacoordinate carbon atoms.
