In this hot article the authors investigate a new Pt(II) complex for its DNA binding and clevage properties and find considerable potential for the compound as an anticancer drug. Through detailed X-ray and thermal decomposition studies they also discovered a water cluster containing 20 water molecules in the framework of the Pt(II) host:
