    1. Polymetallic Architectures

      A MnII12 Supramolecular Array with Four Independent Spin-Coupled Subunits (pages 4583–4586)

      Konstantin V. Shuvaev, Louise N. Dawe and Laurence K. Thompson

      Article first published online: 10 SEP 2010 | DOI: 10.1002/ejic.201000837

      The tetratopic pyridazine ligand L2 forms the incomplete MnII12 partial grid [Mn12(L2–2H)6(L–H)2{N(CN)2}2](NO3)8(H2O)24,containing two isolated μ-O-bridged [2 × 2] square and two isolated μ-O-bridged dinuclear subunits. Multiple π contacts contribute to the assembly via the bipy ends, and the columnar stacked pyridazines. Antiferromagnetic exchange occurs through the μ-O bridges.

    2. (Fluoroalkoxy)aluminates

      Synthesis, Characterization and Application of Nitrile-Ligated Zinc(II) Complexes Incorporating (Fluoroalkoxy)aluminates (pages 4587–4590)

      Nitrile-ligated ZnII complexes with two Al-based weakly coordinating anions (WCAs) have been prepared and characterized. The X-ray crystal structure proves the non-coordinating nature of the anions. Synthesis of the compounds is straightforward and high yielding. An application is the room-temperature polymerization of isobutylene resulting in polyisobutylene with high exo double bond content.

      Thumbnail image of graphical abstract

      A number of acetylacetonato(phosphane)iridium complexes have been prepared by addition of phosphane to the iridium complex [Ir(acac)(η2-coe)2] (1). The readily prepared complexes are active and selectivecatalyst precursors for the intramolecular cyclization of 4-pentynoic and 5-hexynoic acids to give the corresponding exocyclic lactones.

      Dihydrogen phosphate provokes an anion-specific reaction with Zn(salphen) chromophores leading to protonated ligand structures. The demetalation process wasinvestigated by NMR, MS and UV/Vis techniques. Kinetic studies suggest that the initial stage of the reaction comprises a phosphate-bridged dimetallic Zn(salphen) complex in which dihydrogen phosphate is activated for proton transfer.

The metal centres (ReI and TcI) are coordinated through the nitrogen imine atoms to give a five-membered chelate ring, and the hydrazone group stands uncoordinated.

    6. Ru-Catalyzed Hydrocarboxylation

      Thumbnail image of graphical abstract

      Product selectivity is a major problem in transition metal-catalyzed hydrocarboxylation reactions. In this paper we report the ability of Ru(CO)3L2 (where L is a 2 edonor) to catalyze the addition of variouscarboxylic acids onto terminal alkynes. A direct relationship between the regioselectivity of the product and the electronic property of the catalysis metal centre was observed.

      The developed phosphors can generate lights from blue to green and eventually to the yellow-greenish region under the excitation of UV radiation by appropriately tuning the activator content. The phosphors have the advantages of appropriate emission efficiency and relatively low price, thus indicating that they have potential application as a UV-convertible phosphor for white-light LEDs.

    8. Ruthenium Complexes

      A series of heterobimetallic Ru,Pt complexes is presented in which a [Ru(C5R5)]+ fragment (R = H or Me) is η6-coordinated to a phenyl ring, and a Pt center is simultaneously η1-coordinated to an NCN-pincer ligand. Depending on the connectivity between both organometallic fragments, very strong to very weak ruthenium-to-platinum interactions are experimentally observed.

      Thumbnail image of graphical abstract

      [(Aryl-ppy)Pt(acac)] complexes have been prepared that show room-temperature phosphorescence at 490–590 nm. The emission colour tuning effect is attributed to either the elevated HOMO energy or the decreased LUMO energy. The luminescent O2-sensing properties of the complexes in polymer films were studied. A white light-emitting OLED was fabricated with Pt-3 with a CIE of (0.32, 0.32).

      Thumbnail image of graphical abstract

      A new metallocapped cyclodextrin was synthesized by a regioselective debenzylation reaction that was induced by diisobutylaluminium hydride (DIBAL-H). The electrochemical investigation of this original complex demonstrated that grafting of a copper salen-type complex to a cyclodextrin leads to changes in the reactivity of the intermediary species.
