Abstract:

An interparticle glass matrix in ruthenium dioxide-based thick film resistors has been studied intensively by means of analytical and high resolution transmission electron microscopy. The ruthenium dioxide phase interacts with lead-borosilicate glass at high temperature by dissolving ruthenium ions and incorporating a small number of lead and aluminum ions on the surface. Ruthenium ions diffuse through the glass network at least over a distance of 1 μm during firing, but are accommodated in the glass structure by an amount only less than 7 at. % at room temperature. High resolution electron mi

Abstract:

One new Ruthenium and one known Iron bimetallic carbonyl clusters containing triphos (1,1,1-tris(diphenylphosphinomethyl)ethane) ligand have been prepared as catalyst to study the reduction of amide to amine. All clusters were characterized by elemental analysis, 1HNMR, 31PNMR and IR spectroscopy. The reduction of N,N-dimethylbenzamide and N,N-diethyl-(3-methyl) benzamide catalyzed by Ru and Fe carbonyl clusters were investigated at 100 ~ 110 °C for 24 ~ 28h, polymethylhydrogensiloxane (PMHS) as reduction agent. The products were analysized using GC-MS, IR and UV-vis spectroscopy and an excell

Abstract:

In this article, it is shown that the dimension of a metal skeleton of giant palladium cluster, containing 561 atoms in five shells, is 8. The claims of some authors that the palladium cluster in this case is an E8 lattice are groundless. The internal geometry of multi-shell metal clusters with ligands and core was investigated. It is proved that the multi-shell clusters with common center and different centers have a higher dimension. Clusters with ligands and a structural unit octahedron exist with different metals in the core. A spatial image of the cobalt tetra-anion cluster is presented.

Abstract:

The production of gas-phase singly charged ruthenium chloride anionic complexes by laser desorption ionization of RuCl3·3H2O is reported. The [RuxCly]− clusters could only be detected in the absence of the matrix component in the negative mode. The cluster compositions observed were [RuCl4]−, [RuCl5]−, [Ru2Cl6]−, [Ru2Cl7]−, [Ru3Cl9]−, [Ru4Cl11]−, and [Ru5Cl12]−. With the aid of density functional theory calculations, we proposed feasible structures for each ruthenium chloride cluster, in which Ru–Ru bonds and Cl bridges were a common characteristic.

The [Ru3O(OOCCH3)6(isonicotinamide)3] cluster exhibits reversible electrochemical and spectroelectrochemical behaviour in acetonitrile solutions, associated with a series of successive μ-oxo RuIVRuIVRuIII/RuIVRu1IIRuIII/…/RuIIRuIIRuII redox couples with E0 = 2.16, 1.21, 0.19, −0.98, and −1.4 V versus SHE. The metal-isonicotinamide and metal–metal charge–transfer transitions shift to lower energies as the oxidation states of the ruthenium ions decrease. In alkaline aqueous solution, the μ-oxo RuIIIRuIIIRuII cluster can be reversibly reduced to the μ-oxo RuIIIRuIIRuII product (E0 = −0.85 V); how

Full text

Abstract:

Photodissociation of trinuclear carbonyl cluster compounds of Fe, Ru and Os was studied by recording the mass spectra produced from laser ablation of the cluster compounds. Under the experimental conditions, dissociation of the cluster compounds is very extensive, but the dissociation pathway of the osmium cluster is different from those of the iron and ruthenium clusters. The iron and ruthenium clusters not only lost their carbonyl ligands, but their cluster cores were also fragmented. As the osmium cluster dissociated, it ejected three pairs of oxygen atoms, in sequence, before losing the ca

Abstract:

Sub-nano metal clusters have important physicochemical features that lead to a wide range of applications. Herein, we point out an unfailing reproducible protocol to synthesize ruthenium single-atom catalysts and ultra-small clusters supported on various silica–alumina mixed oxides. The catalysts were synthesized via a dendrimer-free, sonication-assisted route, with ruthenium loadings up to 2 wt%. Raman spectroscopy mapping revealed a wide coverage of the materials’ surfaces by ruthenium, while HAADF-STEM evidenced that 100% of the ruthenium was at the sub-nano scale, with up to 74% of the sin

Abstract:

Heterometallic cubane-type clusters were synthesized from the reaction of group 6 and 8 metallaboranes using transition-metal carbonyl compounds. Structural and spectroscopic study revealed the existence of novel “capped-cubane” geometry. In addition, the crystal structure of these clusters distinctly confirms the presence of boride unit as one of the vertices. These clusters possess 60 cluster valence electrons (cve) and six metal–metal bonds. A plausible pathway for the formation of ruthenium-capped cubane has been described.

Abstract:

In this review major developments associated with the synthesis, properties, structure and applications of polymer-immobilised clusters of platinum, palladium, ridium, rhodium, osmium and ruthenium, are presented. Special attention is paid to polymer analogous reactions with metal clusters and new directions involving the polymerisation and copolymerisation of cluster-containing monomers. Some specific features of fixing heterometallic clusters on polymers are examined and the more interesting application of PCNM in catalysis, and future developments in this direction, are discussed.

Abstract:

A series of well dispersed ruthenium nano-clusters using Polyvinylpyrrolidone (PVP) as stabilizer were synthesized by seed-mediated method. In this method, polymer-stabilized PVP-Ru nano-cluster with a diameter of about 3.14 nm was prepared by the reduction of RuCl3 in ethylene glycol and used as a seed solution (S), which was then added to the EG solution of ruthenium (Ⅲ) salts (E) to control the size of the Ru nano-cluster synthesized in this seed-mediated method. The influences of the amount of S solution that was added to E solution and the existence of PVP in ruthenium salts solution on t

Abstract:

This thesis describes the synthesis of ruthenium based molecular clusters and their characterisation. Chapter 2 introduces the concept that the very large zero-field splitting (D = 2.9 cm–1) in the S = 5/2 ground state of [Ru2Mn(μ3-O)(tBuCO2)6(py)3] can be modelled by antisymmetric exchange effects. This is supported by measurement of the single ion D values from the Fe2Mn analogue. The same model is applied to the Ru2Ni analogue to describe the zero-field splitting in the S = 1 ground state, (DGS = +8.0 cm–1 from DNi = -4.0 cm–1) in Chapter 3.Chapters 3 and 4 give the full characterisation of

Abstract:

The work describes in this dissertation concerns the syntheses, reactivities and characterisation of some triosmium and tetraruthenium carbonyl clusters with conjugatively unsaturated diynes. While the alkyne chemistry of osmium and ruthenium carbonyl clusters has been explored extensively over the past 20 years, the analogous chemistry of diynes has been less thoroughly explored. Chapter 1 gives a general introduction to the area of carbonyl clusters and their alkyne derivatives in chapter 1, with an emphasis on the group 8 transition metals. Recent and related diyne work is also discussed. T
