Unprecedented 1D helical chains of hydrogen bonded water molecules, showing both handedness and anchored onto a helical supramolecular host formed from the self assembly of a dicopper(ii) complex (1) containing pentadentate Schiff base (L) and p-hydroxycinnamate in 1·2H2O, propagate along the crystallographic 21-screw axis and the compound shows two endotherms due to loss of water molecules at 61.5 and 88.5 °C in the differential scanning calorimetry giving an overall change of enthalpy value of â ¼36 kJ mol<sup>â 1</sup> per water molecule.
