We used the genetic algorithm and quantum chemical calculations to study the structures of the Sc2B6 cluster. The global minimum energy structure has the shape of a hexagonal bipyramid with an Sc atom at each apex and a B6 ring that belongs to the D6h point group symmetry. The second most stable structure has the Cs point group symmetry and can be formed by substituting a Sc atom for a B atom in the ring and a B atom for Sc in one of the apexes. From the computational results, the Sc2B6 cluster is found to be a good candidate to form a nanomaterial for treating CO gas.
