Abstract:
A novel Zr-added trimer, [H2N(CH3)2]10H14[(Zr2P2W16O61)3]·7H2O (1), has been made under hydrothermal conditions, and contains the highest number of Zr centers in known Dawson-type poly(POM)s. A remarkable feature of this study is the first discovery of a new type of divacant [α-5,10-P2W16O60]14- fragment, which assembles with Zr4+ ions to form a cyclic trimer. Furthermore, 1 as a heterogeneous catalyst exhibits high activity for the selective oxidative degradation of a sulfur mustard simulant CEES.
