      Reversible, Fine Performance Tuning of an Organometallic Molecular Wire by Addition, Ligand Replacement and Removal of Dicobalt Fragments (pages 3571–3575)

      Yuya Tanaka, Takashi Koike and Munetaka Akita

      Article first published online: 16 JUL 2010 | DOI: 10.1002/ejic.201000661

      The communication performance of a C≡C-containing diiron molecular wire can be finely tuned in a reversible manner by coordination, removal and ligand exchange of dicobalt species. In contrast to the direct Fe–Fe transition mechanism for the diiron wire, the communication mechanism of the dicobalt adducts involves indirect Fe–Co–Fe electron transfer readily controlled by the ligand on the cobalt centres.

    1. Dithiolene Complexes as Catalyst Models

      Molybdenum Dithiolene Complexes as Structural Models for the Active Sites of Molybdenum(IV) Sulfide Hydrodesulfurization Catalysts (pages 3577–3585)

      Neilson Nguyen, Daniel J. Harrison, Alan J. Lough, Antonio G. De Crisci and Ulrich Fekl

      Article first published online: 6 JUL 2010 | DOI: 10.1002/ejic.201000269

      A key industrial process is the removal of organic sulfur from petroleum, through hydrodesulfurization (HDS) on MoS2 catalysts. HDS reactions of thiophenes are difficult to carry out and are not fully understood. We present new molecular models for the proposed active sites in HDS catalysis: bisdithiolene complexes containing2,5-dihydrothiophene and tetrahydrothiophene.

      Martín Regueiro-Figueroa, David Esteban-Gómez, Andrés de Blas, Teresa Rodríguez-Blas and Carlos Platas-Iglesias

      Article first published online: 23 JUN 2010 | DOI: 10.1002/ejic.201000334

      A study on the solution structure and dynamics of LnIII(do3a) complexes (H3do3a = 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid) shows that the Δ(λλλλ) conformation is favored over the Δ(δδδδ) one. The energy barrier associated with the ringinversion is similar to that observed for LnIII(dota) (H4dota = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) complexes, whereas the low energy barrier for the arm rotation is responsible for fast isomer interconversion.

      Two series of 4f–5d complexes, Ln(H2O)5[W(CN)8] (Ln = La, Pr, Nd, Eu, Gd) and Ln(H2O)4[W(CN)8] (Ln = Ho, Er, Tm, Lu), have been synthesized and characterized structurally. TGA and powder XRD results reveal the presence of the phase transformation in the Ln–W system with increasing atomic number of the LnIII atoms.

The structure of seven molecules isreported. The use of [Fe(η5-C5H4PPh2Cl2Pd)(η5-C5H4terpy)] and [Fe(η5-C5H4PPh2Cl2Pd)(η5-C5H4-CH=CHC(O)(py))] in the Heck–Mizoroki reaction is discussed.

    7. Functionalised Mesoporous Silica

      The supporting capability of –SH modified HMS is evaluated by depositing gold through incipient wet impregnation. The effect of the two support functionalisation procedures, co-condensation and grafting,is investigated by XRD, Au LIII EXAFS and XPS. A stronger interaction between gold and the thiol groups is achieved in the grafted-SH silica with consequent better gold dispersion.

      The 1-platina-2,4,6-trithiane cycle was obtained by oxidative addition of a Pt0 fragment into the sulfur–sulfur bond of 1,2,4-trithiolane and 1,2,4-trithiolane 4-S-oxide. Depending on the phosphane used for thepreparation of the ligand, either the six-membered platinacycle is isolated orthioformaldehyde is eliminated with subsequent ring contraction.

      An unprecedented self-catenated 3D layer pillar framework formed by connecting 2D borromean layers through ferrocenyl bridges is presented. The complex can undergo a dehydrated and rehydrated process in a single-crystal-to-single-crystal manner without affecting the overall framework. The amorphous sample can further be regenerated by water to the crystalline material again.
