✦ Synopsis
A 3 x 3 x 3 cubic grid of oxygen atoms has 54 internal bonds and this can be an idealised model of a completely hydrogenbonded water cluster (H,0)2,. A combinatorial study gave 456 distinct isomers of such ideal structures, each of which should have similar energies. Computer simulation of (H20)27 with a realistic intermolecular potential has produced such structures with energies of -237 kcal/mol. Similar cubic structures, but with a few external O-H bonds have also been found and these have the lower energy of -24 1 kcal/mol.
