Unprecedented 3D interpenetrated networks of hydrogen‐bonded water molecules and a hybrid matrix have been found in a novel supramolecular salt, [H 2 pip] 3 [Ge(hedp) 2 ]⋅14 H 2 O (H 2 pip 2+ =C 4 H 12 N 2 2+ ; hedp 5− =C 2 H 3 P 2 O 7 5− ). In their Full Paper on page 7741 ff., J. Rocha et al. demonstrate that this “ice framework” is stable at ambient temperature for long periods of time. The heating of this salt leads to a sequential framework deconstruction process, which occurs in a stepwise fashion from a 3D network into layers (2D) and, ultimately, discrete water aggregates (0D).
