Extended Data Table 1 Calculated energies for FcCOOH clusters, from dimers to hexamers

From: Self-assembly of hydrogen-bonded two-dimensional quasicrystals

  1. Geometries for each cluster were optimized subject to the constraint of C2 to C6 symmetry. An additional constraint to approximate the effect of surface adsorption was to constrain every CpCOOH ring (C and O atoms) in each oligomer to be coplanar. For each functional, the lowest-energy structure is highlighted in blue, and the second-lowest, in grey.
