First-principles total-energy calculations of structural properties of the carbon cluster C6 have been made using the full-potential augmented plane-waves plus local orbital (APW+LO) method with the generalized gradient approximation (GGA). Initiated from a hexagonal configuration, we performed geometry optimization with damped Newton dynamics. The computed ground state atomic configuration for C6 belongs to a monocyclic structure. The average bond length is 1.52 a.u. and the bond angle is , respectively, which are in agreement with the reported results.
