      Investigating the Formation Mechanism of Arene Ruthenium Metallacycles by NMR Spectroscopy (Eur. J. Inorg. Chem. 33/2014)

      Amine Garci, Gajendra Gupta, Claudio Dalvit and Bruno Therrien

      Article first published online: 20 NOV 2014 | DOI: 10.1002/ejic.201490160

      The cover picture shows how straightforward the synthesis of arene ruthenium metalla-assemblies is: It consists of mixing different building blocks in an appropriate solvent with a precise stoichiometry, followed by a germination period, before harvesting the resulting metalla-assembly. The germination period, involving assembly-disassembly, self-repairing, and rearrangement of the building blocks, has been studied by NMR spectroscopy. The elucidation of the formation mechanism has given valuable answers for the future design of arene ruthenium metalla-assemblies. Details are discussed in the article by B. Therrien et al. on p. 5651 ff. For more on the story behind the cover research, see the Cover Profile.

      The complex [Fe3(μ-OH)2(μ-Ph4DBA)2(TMEDA)2(NO)2](OTf) was synthesized and spectroscopically characterized. Its properties resemble those of a proposed intermediate observed during the catalytic reduction of nitric oxide by flavodiiron reductases.

      Switching the Macrocycle Conformation from Nonplanar to Planar in Cobalt(II) and Copper(II) β-Tetra-2′-thienyl-meso-tetraphenylporphyrin Cocrystallates with C60 (pages 5646–5650)

      Puttaiah Bhyrappa, Ujwal K. Sarangi and Babu Varghese

      Article first published online: 28 OCT 2014 | DOI: 10.1002/ejic.201402763

      Two new porphyrin/C60 cocrystallates, MTPP(2′-thienyl)4·C60·(toluene)2 (M = CoII and CuII; TPP = tetraphenylporphyrin), were examined by single-crystal XRD analysis. These cocrystallates exhibited essentially 1D supramolecular structure. In both the structures, an unusual dramatic decrease in nonplanarity of the macrocycle to near planarity was observed.

    1. Metallacycles

      Investigating the Formation Mechanism of Arene Ruthenium Metallacycles by NMR Spectroscopy (pages 5651–5661)

      Amine Garci, Gajendra Gupta, Claudio Dalvit and Bruno Therrien

      Article first published online: 12 SEP 2014 | DOI: 10.1002/ejic.201402639

      Thumbnail image of graphical abstract

      The stereochemical properties of twelve dinuclear arene ruthenium complexes have been studied in solution by NMR spectroscopy. All complexes showed lability of the pyridyl-based ligands in solution and rapid exchange between the cis and trans isomers. The intermediate species have been identified and, thus, provided insights into the formation mechanism of arene ruthenium metalla-assemblies.

    2. Heterometallic Complexes

      Mono-Oxido-Bridged Heterobimetallic and Heterotrimetallic Compounds Containing Titanium(IV) and Chromium(III) (pages 5662–5674)

      Article first published online: 15 OCT 2014 | DOI: 10.1002/ejic.201402800

      Thumbnail image of graphical abstract

      A series of heterobi- and heterotrimetallic molecules containing an unsupported oxido bridge have been synthesized. The molecular structures are controlled by the stoichiometry of the reagents, and the heterotrimetallic structural motif Ti=O[RIGHTWARDS ARROW]Cr[LEFTWARDS ARROW]O=Ti is hitherto unknown. Electrochemistry and magnetic studies were performed to identify the intermediates and their thermodynamic properties.

    3. Dual Fluorescent Probe

      Structurally Characterized Antipyrine-Based Dual Fluorescent Probe: Enhanced AlIII Selectivity of a Dinuclear ZnII Complex for Intracellular Sensing by a Displacement Approach (pages 5675–5682)

      Article first published online: 15 OCT 2014 | DOI: 10.1002/ejic.201402702

      The antipyrine-based fluorescent probe daph recognizes both Zn2+ and Al3+ at two different wavelengths. However, Al3+ selectivity is enhanced significantly when the corresponding ZnII-daph complex is used as a sensor. Moreover, the detection limit of the ZnII-daph complex for Al3+ is higher than that of free daph. Both daph and ZnII-daph are capable of intracellular Al3+ detection.

    4. Solid-State Structures

      The transformation of a newly observed tetragonal polymorph of CsAlH4 into the previously described orthorhombic CsAlH4 phase can be induced by thermal treatment. The reverse transformation can be induced by mechanical treatment. Both phases were characterized by X-ray diffraction and 27Al and 133Cs MAS NMR spectroscopy.

      Thumbnail image of graphical abstract

      Complexation of Am3+ and Eu3+ with six pyrazine-functionalized calix[4]arene ligands was investigated in room-temperature ionic liquids (RTIL) by carrying out solvent extraction as well as luminescence (only for Eu3+) studies. Solvent extraction with RTIL resulted in a large enhancement in D values, and the nature of the complexes was investigated by luminescence spectroscopy.

      The heat treatment of {[CaCr2(L)2(C2O4)4]·xH2O}n [L = 2,2′-bipyridine, x = 0.83 (1) and 1,10-phenanthroline, x = 0.33 (2)] at 1100 °C in a nitrogen flow resulted in the isolation of the β-CaCr2O4 phase, whereas heating at 1400 °C caused the crystallization of two polymorphs, α-CaCr2O4 and β-CaCr2O4. The spectroscopic, structural and magnetic properties of the single-source precursors and the β phase are investigated.

    8. Carbonyl Compounds

      Role of the Isolable Hydride Intermediate in the Hydrosilylation of Carbonyl Compounds Catalyzed by the High-Valent Mono-Oxido–Rhenium(V) Complex (pages 5714–5723)

      Liangfang Huang, Yu Zhang and Haiyan Wei

      Article first published online: 28 OCT 2014 | DOI: 10.1002/ejic.201402464

      Thumbnail image of graphical abstract

      An undetected η1-silane rhenium adduct rather than the isolable rhenium hydride was the real intermediate in the hydrosilylation of carbonyl compounds catalyzed by the mono-oxido–rhenium(V) complex [Re(O)Cl3(PPh3)2] (1). The formed isolable hydride intermediate 1H was not the activated intermediate for the carbonyl hydrosilylation catalyzed by the mono-oxido–rhenium(V) complex.
