      A preorganized calix[4]arene ligand with dangling phosphonate ester and picolinamide side arms forms stable 1:1 complexes with LaIII, PrIII, EuIII, GdIII, and YbIII. The lipophilic calixarene scaffold also enables extraction of lanthanum and europium picrates from aqueous solutions.

    2. Pd Catalysts

      Preparation of Secondary Phosphine Oxide Ligands through Nucleophilic Attack on Imines and Their Applications in Palladium-Catalyzed Catellani Reactions

      Chan-Yu Hu, Ya-Qian Chen, Guan-Yu Lin, Ming-Kai Huang, Yu-Chang Chang and Fung-E Hong

      Version of Record online: 19 MAY 2016 | DOI: 10.1002/ejic.201600181

      Thumbnail image of graphical abstract

      Several new secondary phosphine oxide (SPO) type ligands, 3a3n, were prepared. In addition, some SPOs as well as coordinated palladium complexes of ligand 3f, that is, 7fa, 7fb, and 8f, with fascinating bonding modes were characterized by X-ray diffraction methods. Some of these ligands were chosen to assist in palladium-catalyzed Catellani reactions.

    3. Photocatalytic Nanocomposites

      Preparation of a Single-Walled Carbon Nanotube/Cd0.8Zn0.2S Nanocomposite and Its Enhanced Photocatalytic Hydrogen Production Activity

      Bosi Peng, Xiaojing Liu and Renjie Li

      Version of Record online: 19 MAY 2016 | DOI: 10.1002/ejic.201600183

      Thumbnail image of graphical abstract

      Single-walled carbon nanotube (SWCNT) and Cd0.8Zn0.2S nanocomposites are fabricated by a coprecipitation process with prefunctionalized SWCNTs as the starting material. The SWCNTs improve both the visible-light-induced activity and stability for H2 production of Cd0.8Zn0.2S, and the activity (632 µmol h–1) is ca. 1.40 times higher than that (451 µmol h–1) of Cd0.8Zn0.2S alone.

      The photoaddition of Ph2CS to Fe2(S2)(CO)6 gives the rare diiron perthiolate Fe2(S3CPh2)(CO)6. Desulfurization of the perthiolate gives Fe2(S2CPh2)(CO)6. These simple reactions provide access to Fe-S-CO compounds that previously were difficult to prepare.

      Thumbnail image of graphical abstract

      We report on the coordination chemistry of scandium bearing bis(oxazolinylphenyl)amide (BOPA) ligands. These complexes exist in two isomeric forms and have been characterised using luminescence spectroscopy. Stoichiometric reactions have been probed, showing the scope and limitations of the chemistry of oxazoline-bearing organometallic-type complexes.

    3. H-Bonding in Enzymes

      Taka-aki Okamura, Takayoshi Yamada, Yuki Hasenaka, Satoshi Yamashita and Kiyotaka Onitsuka

      Version of Record online: 19 MAY 2016 | DOI: 10.1002/ejic.201600081

      Thumbnail image of graphical abstract

      Tertiary ammonium salts of monooxomolybdenum(IV) benzenedithiolates containing bulky hydrophobic acylamino substituents were synthesised. In toluene, the NH+···O=Mo hydrogen bond unexpectedly promoted one-electron oxidation to MoV species by 2,6-lutidinium ion or 0.5 equiv. Me3NO, although normal oxygen atom transfer (OAT) was observed in polar solvents.

    4. Spin Crossover Compounds

      Cooperative High-Temperature Spin Crossover Accompanied by a Highly Anisotropic Structural Distortion

      Il'ya A. Gural'skiy, Bohdan O. Golub, Sergii I. Shylin, Vadim Ksenofontov, Helena J. Shepherd, Paul R. Raithby, Wolfgang Tremel and Igor O. Fritsky

      Version of Record online: 19 MAY 2016 | DOI: 10.1002/ejic.201600406

      Thumbnail image of graphical abstract

      A new 3D cyanoheterometallic framework, [Fe(pz){Au(CN)2}2], displays a highly cooperative spin crossover at elevated temperatures. The low-spin-to-high-spin transition induces a drastic structural distortion that involves a large one-directional expansion (10.6 %) and contraction (9.6 %) of the lattice.

    5. Tuning of Perovskites

      Wide-Range Tuning of the Mo Oxidation State in La1–xSrxFe2/3Mo1/3O3 Perovskites

      Thumbnail image of graphical abstract

      La1–xSrxFe2/3Mo1/3O3 perovskites allow wide tuning of the Mo oxidation state from +3 (x = 0) to +6 (x = 1) with the FeIII oxidation state virtually unchanged. The magnetic properties vary between antiferromagnetic (AFM) for x = 0 to ferromagnetic (FIM) for x = 1.0.

    6. Superheavy Compounds

      The Valence States of Copernicium and Flerovium

      Abhik Ghosh and Jeanet Conradie

      Version of Record online: 18 MAY 2016 | DOI: 10.1002/ejic.201600146

      Thumbnail image of graphical abstract

      Relativistic DFT calculations indicate that copernicium tetrafluoride should be substantially more stable than HgF4. Tetravalent flerovium on the other hand is unlikely to be experimentally accessible. Less noble than xenon, flerovium is predicted to yield both FlF2 and FlCl2 as stable molecules.

      The mixed lanthanoid coordination polymer {[La0.95Tb0.05HL(H2O)2]·H2O}n (H4L = 5-hydroxy-1,2,4-benzenetricarboxylic acid) was prepared and fully characterized. This compound can be used as a ratiometric thermometer based on the emission intensity ratio of ligand phosphorescence and TbIII luminescence over the temperature range 90–280 K with a relative sensitivity of up to 0.53 % K–1.

      Secondary Interactions versus Intramolecular π–π Interactions in CuII–Diradical Complexes

      Richa Rakshit and Chandan Mukherjee

      Version of Record online: 13 MAY 2016 | DOI: 10.1002/ejic.201600019

      Thumbnail image of graphical abstract

      Secondary interactions between the CuII atom and the secondary coordination atoms of tethered groups in mononuclear diradical-containing CuII complexes determine the ground-state electronic configuration of the complex. These secondary interactions can be overcome by weak intramolecular π–π interactions.
