High-Pressure Synthesis and Structures of New Barium Chromium Sulfides, BaCr4S7 and Ba2Cr5S10, with New Type Face-Sharing CrS6 Structure Units
H. Fukuoka,* Y. Miyaki, and S. Yamanaka
[Full Text PDF(J-STAGE)] Open Access Article
 |
New sulfides, BaCr4S7 and Ba2Cr5S10, were prepared by using high-pressure and high-temperature reactions. Their structures contain the same subunits composed of face- and/or edge-sharing CrS6. However, one has a 3-D tunnel structure and the other is a 2-D layered compound.

Columnar Liquid-Crystalline Imidazolium Salts. Effects of Anions and Cations on Mesomorphic Properties and Ionic Conductivities
M. Yoshio, T. Ichikawa, H. Shimura, T. Kagata, A. Hamasaki, T. Mukai, H. Ohno, and T. Kato*
[Full Text PDF(J-STAGE)] [Supporting Information] Open Access Article
Fan-shaped imidazolium salts with perfluorinated anions self-assembled into hexagonal columnar liquid-crystalline structures forming ionic channels. One-dimensional ion conduction was achieved by macroscopic orientation of the columns.

Development of Fabrication of Giant Nanomembranes
H. Watanabe, R. Vendamme, and T. Kunitake*
[Full Text PDF(J-STAGE)] Open Access Article
 |
Giant membranes that are characterized with nanometer thickness and macroscopic size are reviewed for the first time. They are fabricated from only metal oxides, from hybrids of metal oxides and cross-linked acrylate, and from totally organic thermosetting resins.

A Helmeted Dialkylsilylene
M. Kira,* T. Iwamoto, and S. Ishida
[Full Text PDF(J-STAGE)] Open Access Article
 |
A comprehensive study of the structure, spectroscopic properties, and reactions of an isolable divalent silicon compound bearing a helmet-like substituent has disclosed the intrinsic properties of silylene that have never been revealed by studies on transient dialkylsilylenes.

Tuning of Electronic Structures of Quasi-One-Dimensional Bromo-Bridged PdII–PdIV Mixed-Valence Complexes by Substituting Counter Anions
H. Arakawa, D. Kawakami, S. Takaishi, T. Kajiwara, H. Miyasaka, K.-i. Sugiura, M. Yamashita,* H. Kishida, and H. Okamoto
[Full Text PDF(J-STAGE)] Open Access Article
New quasi-one-dimensional bromo-bridged PdII–PdIV mixed-valence complexes with long chain alkylsufonates [Pd(en)2][PdBr2(en)](CnH2n+1SO3)4·2H2O (en = ethylenediamine, n = 7, 8, 9, and 10) were synthesized. With increasing alkyl-chain length (n) of the counter anions, the PdII···PdIV distances decreased, indicating that the oxidation states of the Pd atoms are close to the PdIII state.

V-Shaped Polyoxotungstoarsenates Incorporating a Prism-Like Hexa Transition-Metals Center: [M6(H2O)2(AsW9O34)2(AsW6O26)]17− (M2+ = Mn2+, Co2+, Zn2+)
K. Fukaya and T. Yamase*
[Full Text PDF(J-STAGE)] Open Access Article
 |
Hexa transition-metals incorporated polyoxotungstoarsenates, [M6(H2O)2(AsW9O34)2(AsW6O26)]17− (M2+ = Mn2+, Co2+I, Zn2+), have prepared at pH 7–8 and characterized by elemental analysis, electrochemistry, and X-ray crystallography. A single Na+ cation coordinated by three oxygen atoms (two belonging to B-α [AsW9O34]9− and one belonging to B-[AsW6O26]11−) in the crevice of the anion appears to stabilize the V-shaped structure.
