Water nanotubes are one-dimensional channels of water clusters that exist in nanoporous H-bonded metal-coordination crystals of cobalt(III) complexes and trimesate. It is shown by X-ray crystallography that the pre-melting endothermic peak observed in the ascending differential scanning calorimetry curve results from partial movement of water molecules of the frozen state as a result of a structural transition (see picture).
