Tuning the Selectivity of Gd3N Cluster Endohedral Metallofullerene Reactions with Lewis Acids

21.11.2014 | Steven Stevenson; Khristina A Rottinger; Muska Fahim; Jessica S Field; Benjamin R Martin; Kristine D Arvola, Inorganic Chemistry, 2014

We demonstrate the manipulation of the Lewis acid strength to selectively fractionate different types of Gd3N metallofullerenes that are present in complex mixtures. Carbon disulfide is used for all Lewis acid studies. CaCl2 exhibits the lowest reactivity but the highest selectivity by ...

Exploring the Interaction of N/S Compounds with a Dicopper Center: Tyrosinase Inhibition and Model Studies

21.11.2014 | Elina Buitrago; Alexandra Vuillamy; Ahcène Boumendjel; Wei Yi; Gisèle Gellon; Renaud Hardré; Christian Philouze; Guy ..., Inorganic Chemistry, 2014

Tyrosinase (Ty) is a copper-containing enzyme widely present in plants, bacteria, and humans, where it is involved in biosynthesis of melanin-type pigments. Development of Ty inhibitors is an important approach to control the production and the accumulation of pigments in living systems. In this ...

Structural, Electronic, and Optical Properties of Eu-Doped BiOX (X = F, Cl, Br, I): A DFT+U Study

21.11.2014 | Zong-Yan Zhao; Wen-Wu Dai, Inorganic Chemistry, 2014

In order to understand the photophysical properties and explain the experimental observations of Eu-doped BiOX (X = F, Cl, Br, I), the crystal structure, electronic structure, and optical properties of pure BiOX and Eu-doped BiOX have been calculated using the DFT+U method. By Eu doping, the band ...

Ligand Exchange and Redox Processes in Iridium Triazolylidene Complexes Relevant to Catalytic Water Oxidation

21.11.2014 | Ana Petronilho; Antoni Llobet; Martin Albrecht, Inorganic Chemistry, 2014

Iridium(III) complexes containing a bidentate spectator ligand have emerged as powerful catalyst precursors for water oxidation. Here we investigate the initial steps of the transformation at the iridium center when using complex [IrCp*(pyr-trz)Cl] 1 (Cp* = pentamethylcyclopentadienyl, pyr-trz = ...

Metastable (Bi, M)2(Fe, Mn, Bi)2O6+x (M = Na or K) Pyrochlores from Hydrothermal Synthesis

21.11.2014 | Luke M. Daniels; Helen Y. Playford; Jean-Marc Grenèche; Alex C. Hannon; Richard I. Walton, Inorganic Chemistry, 2014

The hydrothermal syntheses, structures, and magnetism of two new pyrochlore oxides of compositions (Na0.60Bi1.40)(Fe1.06Mn0.17Bi0.77)O6.87 and (K0.24Bi1.51)(Fe1.07Mn0.15Bi0.78)O6.86 are described. With preparation at 200 °C for 6 h in solutions of sodium or potassium hydroxide, the alkali metals ...

Trivalent Uranium Phenylchalcogenide Complexes: Exploring the Bonding and Reactivity with CS2 in the Tp*2UEPh Series (E = O, S, Se, Te)

21.11.2014 | Ellen M. Matson; Andrew T. Breshears; John J. Kiernicki; Brian S. Newell; Phillip E. Fanwick; Matthew P. Shores; Jus ..., Inorganic Chemistry, 2014

The trivalent uranium phenylchalcogenide series, Tp*2UEPh (Tp* = hydrotris(3,5-dimethylpyrazolyl)borate, E = O (1), S (2), Se (3), Te (4)), has been synthesized to investigate the nature of the U–E bond. All compounds have been characterized by 1H NMR, infrared and electronic absorption ...

Reasons behind the Relative Abundances of Heptacoordinate Complexes along the Late First-Row Transition Metal Series

21.11.2014 | Martín Regueiro-Figueroa; Luís M. P. Lima; Víctor Blanco; David Esteban-Gómez; Andrés de Blas; Teresa Rodríguez-Blas ..., Inorganic Chemistry, 2014

A series of transition metal complexes [ML1] (H2L1 = 1,4,10-trioxa-7,13-diazacyclopentadecane-N,N′-diacetic acid, M = Co, Ni, Cu, or Zn) have been prepared and characterized. The X-ray structures of the [CoL1] and [CuL1] complexes reveal that the metal ions are seven-coordinated with a distorted ...

M3(P2O7)22–-Type Open Frameworks Featuring [M2O8] and [M3O12] Multinuclear Transition-Metal Oxide Units. Serendipitous Synthesis of Six Polymorphic Salt-Inclusion Magnetic Solids: Na2M3(P2O7)2·ACl (M = Mn, Fe; A = Rb, Cs) and K2M3(P2O7)2·CsCl (M = Fe, Mn)

21.11.2014 | Jianhua Gao; Jian Li; Dino Sulejmanovic; Shiou-Jyh Hwu, Inorganic Chemistry, 2014

Single crystals of six polymorphic salt-inclusion phosphates of the A2M3(P2O7)2·A′Cl type, Na2Mn3(P2O7)2·CsCl (1), Na2Mn3(P2O7)2·RbCl (2), Na2Fe3(P2O7)2·CsCl (3), Na2Fe3(P2O7)2·RbCl (4), K2Mn3(P2O7)2·CsCl (5), and K2Fe3(P2O7)2·CsCl (6), were grown in reactive molten chloride flux media. Compounds ...

High Temperature X-ray Diffraction Study of the Oxidation Products and Kinetics of Uranium–Plutonium Mixed Oxides

20.11.2014 | Michal Strach; Renaud C. Belin; Jean-Christophe Richaud; Jacques Rogez, Inorganic Chemistry, 2014

The oxidation products and kinetics of two sets of mixed uranium–plutonium dioxides containing 14%, 24%, 35%, 46%, 54%, and 62% plutonium treated in air were studied by means of in situ X-ray diffraction (XRD) from 300 to 1773 K every 100 K. The first set consisted of samples annealed 2 weeks ...

Structural Variability versus Structural Flexibility. A Case Study of Eu9Cd4+xSb9 and Ca9Mn4+xSb9 (x ≈ 1/2)

20.11.2014 | Xiao-Cun Liu; Zhen Wu; Sheng-Qing Xia; Xu-Tang Tao; Svilen Bobev, Inorganic Chemistry, 2014

The focus of this article is on the synthesis and structural characterization of the new ternary antimonides Eu9Cd4+xSb9 and Ca9Mn4+xSb9 (x ≈ 1/2). Although these compounds have analogous chemical makeup and formulas, which may suggest isotypism, they actually belong to two different structure ...
