A 3×3×3 cubic grid of oxygen atoms has 54 internal bonds and this can be an idealised model of a completely hydrogen-bonded water cluster (H2O)27. A combinatorial study gave 456 distinct isomers of such ideal structures, each of which should have similar energies. Computer simulation of (H2O)27 with a realistic intermolecular potential has produced such structures with energies of -237 kcal/mol. Similar cubic structures, but with a few external OH bonds have also been found and these have the lower energy of -241kcal/mol.
