(a) Three-dimensional model for the crystal structure of ice. (b)–(d) Dimers composed of two water molecules. (b) The lowest energy equilibrium `trans' configuration showing a mirror plane symmetry (Petrenko & Whitworth, 2002BB40). (c) and (d) Unstable configurations, where the dipole moments of the two water molecules do not point in such a way that they oppose each other as much as possible. (e) Water molecule showing magnets located at the lone-pair positions on the acceptor sites (in the oxygen atom) and on the proton donor sites (the hydrogen atoms).
