Abstract

We report the crystal structure and dielectric properties of a pure H2O@C60 crystal at low temperature. The caged water molecules free from the hydrogen bonds rotate even at 8 K. The antifreeze rotating water molecules respond to an external electric field due to their permanent dipole moment.
