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.

Ion-Association Extraction of Nitrobenzoate Ions with Tetrabutylammonium Ion into Nonionic Surfactant Micelles as Studied by Capillary Zone Electrophoresis
T. Takayanagi* and S. Motomizu
[Full Text PDF(J-STAGE)]

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.

Remarkable Stabilization of a Ligand-Based Mixed-Valence State in the Metal-Based Mixed Valent Ru2II,IIIMII(μ3-O) (M = Co, Ni) Trinuclear Cluster Complexes
M. Tanaka, N. Kariya, M. Abe,* and Y. Sasaki*
[Full Text PDF(J-STAGE)]
Two consecutive one-electron reductions of the mixed-metal trinuclear complexes [RuIII2MII(μ3-O)(μ-CH3COO)6(S)(bzpy)2] {(M = Co, S = H2O) and (M = Ni, S = N,N′-dimethylformamide); bzpy = 4-benzoylpyridine} in acetonitrile give stable “double” mixed-valence states where both Ru2II,III and (bzpy−)(bzpy) states coexist. Splitting of the ligand-based redox waves, (bzpy)2/(bzpy−)(bzpy)/(bzpy−)2, is 0.35 and 0.34 V for the Co and Ni complexes, respectively.

Shape-Selective Alkylation of Biphenyl over H-[Al]-SSZ-24 Zeolites with AFI Topology
A. Ito, H. Maekawa, H. Kawagoe, K. Komura, Y. Kubota, and Y. Sugi*
[Full Text PDF(J-STAGE)]
The isopropylation of biphenyl (BP) was examined over H-[Al]-SSZ-24 zeolites. Catalytic activities appeared by isomorphous substitution of [B]-SSZ-24 with aluminum nitrate. The selectivities for 4,4′-diisopropylbiphenyl (4,4′-DIPB) are around 70–80%. Selective formation of 4,4′-DIPB occurs inside the channels by shape-selective catalysis.

[Full Text PDF(J-STAGE)] [Supporting Information]

We have succeeded in the selective preparation of monodispersed and oxidation-resistant Cu nanoparticles that are 5–6 and 2–3 nm in diameter using Cu octanoate and Cu myristate as starting precursors, respectively. Formation of the particles and their growth have been traced by using UV–vis absorption spectroscopy and TEM.
