- Dinuclear Face-Sharing Bi-octahedral Tungsten(VI) Core and Unusual Thermal Behavior in Complex Th Tungstates

Keeping face: The A6Th6(WO4)14O (A=K and Rb) series demonstrate an unusually complex structure. Both phases are based on complex [Th6W7O46(W2O9)]32− cages. The cage, with a cross section similar to a six-leafed lily, contains a rare case of face-sharing [WVI2O9]6− bi-octahedral core (see figure). Besides, its rotation and expansion in certain directions can result in unusual thermal behavior.
- Structural, Spectroscopic and Computational Examination of the Dative Interaction in Constrained Phosphine–Stibines and Phosphine–Stiboranes

A complex situation: The strength of a dative phosphine–stiborane (P–Sb) interaction increases with stepwise replacement of phenyl groups on antimony atom with chloride groups. As the Lewis acidity is increased in regular steps (see figure), essentially linear response is observed initially, however then a sudden change in the P–Sb distance takes place during one particular step. This is consistent with a sudden switch from a non-bonding to a bonding interaction, that is, a discrete rather than continuum response.
- Visible-Light Sensitization and Photoenergy Storage in Quantum Dot/Polyoxometalate Systems
Prof. Tetsuya Kida, Hiromasa Furuso, Kota Kumamoto, Azzah Dyah Pramata, Prof. Masayoshi Yuasa and Prof. Kengo Shimanoe

Enhanced capabilities: CuInS2 quantum dots (QDs) are used to sensitize polyoxometalates (POMs) with wide band gaps. Visible-light-induced photocatalytic reactions proceed through the formation of one-electron-reduced POMs, which also show photoenergy-storing properties (see figure).
- Eliminating Voltage Decay of Lithium-Rich Li1.14Mn0.54Ni0.14Co0.14O2 Cathodes by Controlling the Electrochemical Process

A lithium-rich cathode material Li1.14Mn0.54Ni0.14Co0.14O2 was prepared by a co-precipitation method. Voltage decay in long-term cycling is largely eliminated by control of the charge–discharge voltage range (9.8 % decay in discharge voltage between 2.0–4.6 V, 1.7 % for 2.0–4.4 V: 3.53 to 3.47 V).
- Phase-Transfer and Other Types of Catalysis with Cyclopropenium Ions

Aromatic ions: Tris(dialkylamino)cyclopropenium ions are shown to be effective carbocationic phase-transfer catalysts for a variety of mainstay transformations. The cyclopropenium platform is shown to be modular and accessible on scale. An X-ray structure and electron-density map revealed some unique features of this architecture (see scheme).
