ChemInform Abstract: Encapsulation of Anion/Cation in the Central Cavity of Tetrameric Polyoxometalate, Composed of Four Trititanium(IV)‐Substituted α‐Dawson Subunits, Initiated by Protonation/Deprotonation of the Bridging Oxygen Atoms on the Intramolecular Surface.

Abstract

IV)-Substituted α-Dawson Subunits, Initiated by Protonation/Deprotonation of the Bridging Oxygen Atoms on the Intramolecular Surface. -The [(P2W15Ti3O60.5)4(NH4)] 35-Dawson tetramer with encapsulated cation is synthesized and characterized by FTIR, 15 N{ 1 H}, 31 P, and 183 W NMR spectroscopy. Single crystal XRD shows that (III) crystallizes in the triclinic space group P1 with Z = 4. -(SAKAI, Y.; OHTA, S.; SHINTOYO, Y.; YOSHIDA, S.; TAGUCHI, Y.; MATSUKI, Y.; MATSUNAGA, S.; NOMIYA*, K.; Inorg.
