      A series of neutral hexacoordinate silicon(IV) complexes have been synthesized and structurally characterized by NMR spectroscopy and single-crystal X-ray diffraction. These studies were performed with a special emphasis on comparing the respective O/NMe/S analogues 4a/5a/6a and 4b/5b/6b and the O/S pairs 4a/4b, 5a/5b, and 6a/6b with respect to their structures and NMR spectroscopic parameters.

    2. Metal–Organic Frameworks

      Construction of Metal–Organic Frameworks Consisting of Dinuclear Metal Units Based on 5-Hydroxyisophthalate and Flexible Dipyridyl Ligands

      Xiaoju Li, Tena Guan, Xiaofang Guo, Xinxiong Li and Zhenjiang Yu

      Article first published online: 3 APR 2014 | DOI: 10.1002/ejic.201400092

      Thumbnail image of graphical abstract

      Four CoII and CuII metal–organic frameworks consisting of dinuclear metal units have been constructed from rigid 5-hydroxyisophthalate (ip-OH) and flexible dipyridyl ligands. The ip-OH bridging modes and the metal coordination geometries are very different in the four complexes. Magnetic studies indicate the existence of antiferromagnetic exchange between the metal centers.

    1. A Luminescent Metallacycle

      A Luminescent Rhenium(I) Metallacycle with Oxygen and Nitrogen Donor Atoms: Photophysical and Theoretical Studies

      Dibyendu Bhattacharya

      Article first published online: 3 APR 2014 | DOI: 10.1002/ejic.201400067

      A new N,O-bischelator-bridged D-type self-assembled ReI metallacycle exhibits unusual multiple emission with moderate luminescence (Φem = 0.26, average radiative decay lifetime, τr = 0.052 μs). An improvement of the luminescence efficiency on traversing from ReC3N3 to ReC3N2O to ReC4N2 has been established based on photophysical and DFT results.

    1. Iridium Complexes

      Intramolecular π Stacking in Cationic Iridium(III) Complexes with Phenyl-Functionalized Cyclometalated Ligands: Synthesis, Structure, Photophysical Properties, and Theoretical Studies

      Peng Li, Guo-Gang Shan, Hong-Tao Cao, Dong-Xia Zhu, Zhong-Min Su, Rukkiat Jitchati and Martin R. Bryce

      Article first published online: 3 APR 2014 | DOI: 10.1002/ejic.201400007

      Thumbnail image of graphical abstract

      A combined experimental and theoretical study of the cationic iridium complexes [Ir(dppy)2phen]PF6 (1) and [Ir(tppy)2phen]PF6 (2) is described. The complexes are green photoemitters. Strong intramolecular π–π stacking leads to enhanced distortions in the geometry of the complexes, which is detrimental to their use in light-emitting electrochemical cells (LECs).

    2. DNA Cleavage

      Synthesis, Crystal Structures, and DNA Cleavage Activities of Manganese(II) Complexes: A Good Example of the Synergy between Metal Ions Prompting DNA Cleavage

      Article first published online: 3 APR 2014 | DOI: 10.1002/ejic.201400044

      Thumbnail image of graphical abstract

      The higher DNA cleavage abilities of multinuclear MnII complexes than their mononuclear analogue and the highest DNA cleavage efficiency of the complex with the shortest Mn···Mn distance and the strongest magnetic coupling between the MnII ions confirm the great effect of the synergy between metal centers on DNA cleavage efficiencies.

    3. Self-Assembly

      Self-Assembled Cages from the Electroactive Bis(pyrrolo)tetrathiafulvalene (BPTTF) Building Block

      Sébastien Bivaud, Sébastien Goeb, Jean-Yves Balandier, Marcos Chas, Magali Allain and Marc Sallé

      Thumbnail image of graphical abstract

      An expeditive synthesis of electroactive di- and tetratopic ligands based on bis(pyrrolo)tetrathiafulvalene (BPTTF) is described. The coordination-driven self-assembly of these ligands with cis-protected PtII complexes affords the first examples of 3D cages incorporating the electron-rich TTF unit. These ligands are also able to undergo an original conversion to heteroleptic dithiolene complexes.

      Article first published online: 27 MAR 2014 | DOI: 10.1002/ejic.201400054

      Thumbnail image of graphical abstract

      Carboxylic-rich graphene oxide and MnIII tetrakis(N-methyl-4-pyridinio)porphyrin form self-assembled structures through π–π stacking interactions. When adsorbed on iron/hematite photoanodes, these structures show substantial activity towards the photoelectrochemical oxidation of water.

    2. Waste Prevention

      Sodium “Activation” of Silano-Phosphonate Modified Mesoporous TiO2 Leading to Improved Rare-Earth Element Extraction

      Mícheál P. Moloney, Jérémy Causse, Cedric Loubat and Agnès Grandjean

      Article first published online: 27 MAR 2014 | DOI: 10.1002/ejic.201400027

      Thumbnail image of graphical abstract

      Mesoporous silano-phosphate functionalised TiO2 particles are used to separate Ce3+ from Sr2+ and Cs+, as well as other rare earths. Unlike SiO2, the resistance of TiO2 to strong base allowed for the phosphonate to be activated by a base, increasing its sorption ability threefold.

    3. Catalytic Hydrolysis

      Article first published online: 26 MAR 2014 | DOI: 10.1002/ejic.201301375

      Thumbnail image of graphical abstract

      Catalytic hydrolysis of a phosphodiester bond was investigated by using a mixed-valence heterodinuclear FeIIIMnII complex of the dinucleating ligand as catalyst. Computational modeling and kinetic results indicate that a μ-hydroxo FeIIIMnII complex is the active catalyst that binds the substrate in a monodentate fashion at the Mn ion.

      The photophysical properties of thirteen [Re6Se8]2+ clusters containing N-donor ligands are reported. The impact of para substituents on luminescence was investigated by using a series of benzonitrile and phenyl-substituted tetrazolate complexes. CV and DFT studies support metal-to-ligand charge transfer (MLCT) character in the excited-state wave function for the p-nitrobenzonitrile complex.

      Thumbnail image of graphical abstract

      Zn complexes with malonato ligands functionalized in the 2-position are suitable precursors for solution processed ZnO. A detailed investigation of the decomposition mechanism shows the influence of nitro and hydroxylimino groups on the ceramisation process. The precursors allow the formation of nanocrystalline ZnO which can be used as semiconductor material in field-effect transistors.

      The crystal-field energy splitting of the ground-state multiplets of the complexes Dy and Yb was evaluated, and they demonstrate Ising and non-Ising character. Both anisotropy axis directions for the MJ ground states were determined in agreement with the oblate and prolate electronic distribution for DyIII and YbIII ions. This results in SMM and non-SMM behaviour for Dy and Yb, respectively.

      Complexes of LnIII with N,N′,O,O′-tetradentate dipyridyl-based ligands were synthesized. Their structures were studied by X-ray diffraction, and their binding constants were determined by UV/Vis titration. Structure–property relationships were partly revealed by DFT calculations of the potential energy surface (PES) for three ligands, which show different efficiencies in extracting AmIII.
