of Ice-five (Ice V) and ice-thirteen (Ice XIII)
Ice-five (Ice V), above and immediately below. Note that in these structural diagrams the hydrogen bonding is somewhat ordered
whereas in reality it is random (obeying the 'ice rules': two hydrogen
atoms near each oxygen, one hydrogen atom on each O····O
Ice-thirteen (Ice XIII) This structure (below) does have the ordered protons shown.
