چکیده
Abstract Chemical reactions of ball-mill activated [Nb 6 I 11 ] with alcohol solutions Mg alcoholates result in the formation three new hexanuclear Nb cluster compounds 8 (HOCH 3 ) ][Nb (OCH 18 ]·2CH OH ( 1 ), (PPh 4 2 (OC H 5 12 ]·C and (PPN) ). They contain anions, which have edges octahedra, i.e. inner coordination sites, μ -bridged by O atoms methanolato or ethanolato ligands. Thereby, they represent further characterized members so far very small group alcoholates. The terminal metal sites are bonded to iodido ligands Sterically demanding organic cations + , PPN a cationic complex methanol 2+ compensate negative charges anions. Compound is first example M ion pair both text-book known edge-bridged [ X face-bridged units. structures title were determined means single-crystal X-ray structure analysis. Graphical

A hexanuclear gold carbonyl cluster.
The hexanuclear gold carbonyl cluster [PPh4]2[Au6(CF3)6Br2(CO)2] (4) has been obtained by spontaneous self-assembly of the following independent units: CF3AuCO (1) and [PPh4][Br(AuCF3)2] (3). The cyclo-Au6 aggregate 4, in which the components are held together by unassisted, fairly strong aurophilic interactions (Au···Au ∼310 pm), exhibits a cyclohexane-like arrangement with chair conformation....
متن کاملCLUSTER ALGEBRAS AND CLUSTER CATEGORIES
These are notes from introductory survey lectures given at the Institute for Studies in Theoretical Physics and Mathematics (IPM), Teheran, in 2008 and 2010. We present the definition and the fundamental properties of Fomin-Zelevinsky’s cluster algebras. Then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generator...
متن کاملA Hexanuclear Gold Cluster Supported by Three-Center–Two-Electron Bonds and Aurophilic Interactions**
Gold clusters or nanoparticles have been proposed as catalytically active species in a variety of homogeneous processes, which might proceed by mechanisms that are very different from those occurring under homogeneous conditions. The preparation of new types of small gold clusters has attracted recent attention because of their structural novelty and potential for the discovery of new reaction ...

Received ; accepted – 2 – ABSTRACT We evaluate the dependence of the cluster correlation length r c on the mean intercluster separation D c , for three models with critical matter density, vanishing vacuum energy (Λ = 0) and COBE normalized: a tilted CDM (tCDM) model (n = 0.8) and two blue mixed models with two light massive neutrinos yielding Ω h = 0.26 and 0.14 (MDM1 and MDM2, respectively). ...
متن کاملEuropean Project Cluster on Mixed-Criticality Systems
Modern embedded applications already integrate a multitude of functionalities with potentially different criticality levels into a single system and this trend is expected to grow in the near future. Without appropriate preconditions, the integration of mixed-criticality subsystems can lead to a significant and potentially unacceptable increase of engineering and certification costs. There are ...
