      A diterbium complex, which was synthesized by using p-tert-butylsulfonylcalix[4]arene, shows highly efficient luminescence with a quantum yield of 85 % as well as superparamagnetic behaviour due to slowmagnetic relaxation at low temperatures, and both were achieved by controlling the conformation of the calixarene in the complex.

    2. Heterometallic Interactions

      Do Metal–Metal Multiply-Bonded “Ligands” Have a trans Influence? Structural and Magnetic Comparisons of Heterometallic Cr[QUAD BOND]Cr···Co and Mo[QUAD BOND]Mo···Co Interactions (pages 5569–5572)

      Michael Nippe, Eric Victor and John F. Berry

      Article first published online: 14 NOV 2008 | DOI: 10.1002/ejic.200801001

      Thumbnail image of graphical abstract

      The first heterometallic Cr[QUAD BOND]Cr···Co (1) and Mo[QUAD BOND]Mo···Co (2) complexes synthesized feature surprisingly short heterometallic Cr···Co or Cr···Mo distances and unexpectedly different spin states. Furthermore, the Co–Cl bond lengths in these compounds are inversely proportional to the Cr···Co or Mo···Co separation, suggesting that the M[QUAD BOND]M group has a trans influence on the Co2+ ion.

      Thumbnail image of graphical abstract

      A novel family of enantiomerically pure imidazolium salts has been generated bearing an oxazoline unit and in which both heterocyles are connected by a (dimethyl)methylene bridge. The coordination behavior of the corresponding carbenes has been investigated by preparing Rh and Pt complexes.

    4. Lithium Solid Electrolytes

      A Strategy to Improve the Overall Performance of the Lithium Ion-Conducting Solid Electrolyte Li0.36La0.560.08Ti0.97Al0.03O3 (pages 5599–5602)

      Yaoming Wang, Zhanqiang Liu, Fuqiang Huang, Jianhua Yang and Junkang Sun

      Article first published online: 12 NOV 2008 | DOI: 10.1002/ejic.200800482

      Thumbnail image of graphical abstract

      A strategy to improve the overall performance of the lithium ion-conducting solid electrolyte Li0.36La0.560.08Ti0.97Al0.03O3 is proposed. With the coating of LGPS on LLTO to serve as continuous grain boundaries, the ionic conductivity of LLTO was highly enhanced, the electrochemicalwindow was greatly broadened, and the electronic conductivity was sufficiently suppressed.

    5. Immobilised Phosphane Complexes

      On the Immobilisation of Catechol Phosphane Palladium Complexes on Titania (pages 5603–5608)

      Samir Chikkali, Dietrich Gudat and Samith Komath Mallissery

      Article first published online: 18 NOV 2008 | DOI: 10.1002/ejic.200800743

      Thumbnail image of graphical abstract

      Pd complexes of catechol phosphanes were deposited on TiO2. 31P HRMAS NMR studies of the dry materials and of suspensions in different solvents showed that the binding strength and the resistance towards leaching vary noticeably with the properties of the supporting material.

    6. Thallium Thio- and Selenophenolates

      Isostructural Potassium and Thallium Salts of Sterically Crowded Thio- and Selenophenols: A Structural and Computational Study (pages 5609–5616)

      Denis Bubrin and Mark Niemeyer

      Article first published online: 12 NOV 2008 | DOI: 10.1002/ejic.200800756

      Thumbnail image of graphical abstract

      Sterically crowded, thio- and selenophenolate ligands have been used to stabilize dimeric, unsolvated complexes of potassium and thallium. The different nature of the M–E and M···C(arene) bonding was studied by density functional theory calculations that show a higher degree of covalence for the thallium compounds and no significant influence from the lone pair on Tl.

    7. Multinuclear Ruthenium Complexes

      Reaction of (Carbonyl)triruthenium with Acetylferrocene Thiosemicarbazone: Synthesis, X-ray Diffraction, and Insight into the Solution Structures (pages 5617–5621)

      Jing-Mu Yang, Bin Hu, Xiao-Xue Hu and Chun-Gu Xia

      Article first published online: 10 NOV 2008 | DOI: 10.1002/ejic.200800789

      Thumbnail image of graphical abstract

      The first trirutheniun complex with anacetylferrocene thiosemicarbazone ligand was prepared. Upon heating, the breakdown of 1 gives rise to the intermediateRu(CO)2(L-H) (3). Finally, the dimerization of 3 occurs rapidly to generate the first bis(cycloruthenated acetylferrocene thiosemicarbazone)carbonyl complex 2.

    8. Chelation of Aminoquinoline Ligands

      Preparation of New Bis(8-aminoquinoline) Ligands and Comparison with Bis(8-hydroxyquinoline) Ligands on Their Ability to Chelate CuII and ZnII (pages 5622–5631)

      Céline Deraeve, Alexandrine Maraval, Laure Vendier, Vanessa Faugeroux, Marguerite Pitié and Bernard Meunier

      Article first published online: 18 NOV 2008 | DOI: 10.1002/ejic.200800924

      Thumbnail image of graphical abstract

      New bis(8-aminoquinoline) ligands linked on the C2 carbon atom of both quinolines have been prepared. When the linker includes a one-atom amino group, the ligands appear to be excellent chelators of CuII and form mononuclear species with high selectivity relative to ZnII.

    9. Aerobic Fe(III) to Fe(II) Reduction

      Aerobic FeIII–FeII Reduction in the Presence of 2,4,6-Tri(2-pyridyl)-1,3,5-triazine and Benzilic Acid: Synthesis and Characterization of a Heptacoordinate FeII–Nitrato Complex (pages 5632–5641)

      Catherine P. Raptopoulou, Yiannis Sanakis and Athanassios K. Boudalis

      Article first published online: 21 NOV 2008 | DOI: 10.1002/ejic.200800560

      Thumbnail image of graphical abstract

      The aerobic reduction of FeIII to FeII affords heptacoordinate HS [FeII(tptz)(NO3)(MeOH)2](NO3) [tptz = 2,4,6-tri(2-pyridyl)-1,3,5-triazine] and hexacoordinate LS [FeII(tptzH)2](ClO4)4 complexes. The +2oxidation state is stabilized by coordination of tptz and simultaneous presence of benzilic acid in the mixture, whereas the absence of benzilic acid affords an oxido-bridged diferric complex.

    10. Layered Magnets

      Magnetic Properties of NiIICrIII Layered Double Hydroxide Materials (pages 5642–5648)

      Juan J. Almansa, Eugenio Coronado, Carlos Martí-Gastaldo and Antonio Ribera

      Article first published online: 21 NOV 2008 | DOI: 10.1002/ejic.200800658

      Thumbnail image of graphical abstract

      By employing homogeneous precipitation methods and varying the metal ratio in the synthetic gel, we succeeded in isolating four layered double hydroxide compounds having the general formula [NiII3–xCrIIIx(OH)6](CO3)x/2·yH2O [x = 0.57 (1), 0.69 (2), 0.81 (3) and 0.93 (4)]. This class of layered materials can be used as model systems to correlate magnetic properties with metal composition along the hydroxide layers.

    11. Hybrid Silica Nanoparticles

      Synthesis, Characterisation and Optical Properties of Silica Nanoparticles Coated with Anthracene Fluorophore and Thiourea Hydrogen-Bonding Subunits (pages 5649–5658)

      Article first published online: 12 NOV 2008 | DOI: 10.1002/ejic.200800721

      Thumbnail image of graphical abstract

      Bifunctionalised hybrid nanoparticles containing anthracene and thiourea have been synthesised and characterised, and their emission properties in the presence of anions have been studied. The apparent binding constants (adsorption constants) for the interaction of the fluorescent nanoparticles with anions in acetonitrile were determined by performing a Langmuir-type analysis of fluorescence titration data.

    12. Metallosupramolecular Architectures

      Effect of Ligand Spacer on Metallosupramolecular Architectures: From a Dinuclear Copper(II) Double Helicate to a Tetranuclear Copper(II) Complex (pages 5659–5665)
